Description

Technical Field

[0001] The present application relates to the field of image recognition technology, and in particular to an endoscope display enhancement method and system. Background Art

[0002] In the medical field, endoscopes are commonly used to examine organ lesions. During the endoscopic imaging process, the relative motion between the camera and the examined organ, electronic noise, interference and other factors result in poor visual effects of the endoscopic image.

[0003] At the same time, existing organ diseases are highly complex. Doctors are required to have strong professional knowledge and combine a variety of examination information to accurately diagnose patients. As a result, when doctors use endoscopes to scan organ images, they need to concentrate on observing abnormal areas in the image, and when abnormal areas are found, they need to review medical images provided by other examination equipment.

[0004] Obviously, the above method is not only cumbersome to operate and easily fatigues doctors, but also likely causes inconsistent diagnosis results due to inconsistent professional and technical levels of doctors, that is, the reliability of the diagnosis results is difficult to guarantee. Summary of the Invention

[0005] In view of this, an embodiment of the present application provides an endoscope display enhancement method and system to solve the above technical problems.

[0006] A first aspect of an embodiment of the present application provides an endoscope display enhancement method, comprising:

[0007] Obtaining the original image of the endoscope, processing the original image according to the preset algorithm to obtain an enhanced image;

[0008] Extracting target organ images based on enhanced images;

[0009] Detect the lesion area in the target organ image according to the preset recognition algorithm, and evaluate the lesion condition of the target organ based on the lesion area;

[0010] The lesion condition is combined with the target organ image as auxiliary diagnostic information and visualized according to the preset interface layout principles.

[0011] For example, the step of obtaining an original endoscope image and processing the original image according to a preset algorithm to obtain an enhanced image includes:

[0012] Stretching the corresponding channels of the original endoscope image in the first color space;

[0013] Converting the stretched first color space image to a second color space, and stretching the corresponding channels in the second color space;

[0014] The stretched second color space image is converted to the first color space to obtain an enhanced image.

[0015] For example, the corresponding channels of the original endoscope image are stretched in the first color space, wherein the first color space is the RGB color space, and the mapping function for contrast stretching the green channel in the RGB color space is expressed by the following formula:

[0016] g * (x,y)=[1+d g ×((g(x,y)) -1 -1) 2 ] -1

[0017] In the above formula, g(x, y) and g * (x, y) are the normalized grayscale values ​​of the green channel of the original image and the enhanced image at the pixel (x, y); d g It is the green channel grayscale mapping parameter.

[0018] For example, the stretched first color space image is converted to the second color space, and the corresponding channel is stretched in the second color space, wherein the second color space is the HSV color space, and the mapping function for stretching the grayscale contrast of the saturation channel in the second color space is expressed by the following formula:

[0019] s * =[1+d s ×(s -1 -1) 2 ] -1

[0020] In the above formula, s and s * are the grayscale values ​​of the saturation channel before and after mapping; d s It is the S channel grayscale mapping parameter.

[0021] For example, the step of extracting a target organ image based on the enhanced image includes:

[0022] The enhanced image is processed into superpixels by a preset segmentation algorithm to obtain a number of superpixels;

[0023] Superpixels are classified based on convolutional neural networks to distinguish between superpixels inside organs and superpixels at the edges of organs;

[0024] Select several seed points of organ edge superpixels to construct the initial contour;

[0025] Based on the initial contour, the target organ image is segmented and extracted by solving the minimum value of the preset function.

[0026] For example, the superpixels are classified based on a convolutional neural network to distinguish between superpixels inside the organ and superpixels at the edge of the organ, wherein the objective function of the convolutional neural network is:

[0027]

[0028] In the above formula, represents the probability distribution of the pixel x output by the soft-max layer of the convolutional neural network, i represents the number of layers of the convolutional neural network, and λ i is the weight factor of the i-th layer, N is the total number of pixels, N i is a category L n The total number of pixels within, k represents the basic fact category label, and k∈[0,1] represents the basic fact category label, where 0 represents the superpixel inside the organ, 1 represents the superpixel at the edge of the organ, and x is the pixel point.

[0029] For example, the method of detecting the lesion area in the target organ image according to the preset recognition algorithm and evaluating the lesion condition of the target organ based on the lesion area is as follows:

[0030] Acquire several lesion images and extract the depth features of the lesion images one by one;

[0031] The deep features of each lesion image are encoded into multiple groups of integers through a hash algorithm and stored in a Bloom filter;

[0032] When receiving the image of the target organ to be detected, extracting the depth feature of the image of the target organ to be detected;

[0033] The deep features of the image of the organ to be detected are encoded by a local sensitive hash function, and then a proximity retrieval is performed in the Bloom filter to evaluate the pathological condition of the target organ based on the retrieval results.

[0034] For example, the depth feature of the image of the organ to be detected is encoded by a local sensitive hash function, and after encoding, a proximity search is performed in a Bloom filter to evaluate the pathological condition of the target organ according to the search result, wherein the local sensitive hash function h is expressed by the following formula:

[0035]

[0036] In the above formula, w is a randomly generated normalized vector, b is the offset of random sampling, and ε is a hyperparameter used to control the width of the encoding interval.

[0037] For example, combining the lesion condition as auxiliary diagnostic information with the target organ image and combining it with the preset interface layout principles for visual display includes:

[0038] Based on the visual attention correlation principle and the objective operation principle, the interface layout principle is constructed and converted into a computable interface layout multi-objective optimization function;

[0039] The target optimization function is encoded through a preset algorithm to seek the optimal spatial solution, and then the optimal solution for the combined interface layout of auxiliary diagnostic information and target organ images is obtained, and a visual display is performed based on the optimal solution.

[0040] A second aspect of an embodiment of the present application provides an endoscope display enhancement system, comprising:

[0041] The enhancement module is used to obtain the original image of the endoscope and process the original image according to the preset algorithm to obtain the enhanced image. Specifically:

[0042] Stretching the corresponding channels of the original endoscope image in the first color space;

[0043] Converting the stretched first color space image to a second color space, and stretching the corresponding channels in the second color space;

[0044] converting the stretched second color space image into the first color space to obtain an enhanced image;

[0045] an extraction module, configured to extract a target organ image based on the enhanced image;

[0046] A detection module is used to detect the lesion area in the target organ image according to a preset recognition algorithm, and to evaluate the lesion condition of the target organ based on the lesion area;

[0047] The display module is used to combine the lesion condition as auxiliary diagnostic information with the target organ image and perform a visual display based on the preset interface layout principles.

[0048] A third aspect of an embodiment of the present application provides a terminal, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method described in the first aspect when executing the computer program.

[0049] A fourth aspect of an embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method described in the first aspect are implemented.

[0051] As can be seen from the above, the embodiment of the present application enhances the original endoscope image, thereby suppressing noise, weakening or removing certain unnecessary information, and highlighting the useful information in the image, thereby improving the visual effect of the endoscope image.

[0052] At the same time, the embodiment of the present application detects the lesion area in the target organ image according to a preset recognition algorithm, evaluates the lesion condition of the target organ based on the lesion area, and combines the lesion condition with the target organ image as auxiliary diagnostic information, and combines it with the preset interface layout principles for visual display. Therefore, it can perform intelligent diagnosis, avoid adverse situations such as fatigue caused by frequent manual operations, and ensure the consistency of the diagnosis results, thereby improving the reliability of the diagnosis results.

[0056] Figure 3 This is a schematic diagram of the structure of a terminal provided in an embodiment of the present application. DETAILED DESCRIPTION

[0057] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0058] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of an endoscope display enhancement method provided in an embodiment of the present application. Figure 1 As shown, a method for enhancing endoscope display comprises the following steps:

[0059] Step 1: Obtain an original endoscope image and process the original image according to a preset algorithm to obtain an enhanced image;

[0060] Step 2, extracting the target organ image based on the enhanced image;

[0061] Step 3: Detect the lesion area in the target organ image according to a preset recognition algorithm, and evaluate the lesion condition of the target organ based on the lesion area;

[0062] Step 4: Combine the lesion condition as auxiliary diagnostic information with the target organ image and perform a visual display based on the preset interface layout principles.

[0063] Obviously, the embodiment of the present application enhances the original endoscope image, thereby suppressing noise, weakening or removing certain unnecessary information, and highlighting the useful information in the image, thereby improving the visual effect of the endoscope image;

[0064] At the same time, since the diseased area in the target organ image is detected according to the preset recognition algorithm, and the diseased condition of the target organ is evaluated based on the diseased area, and the diseased condition is combined with the target organ image as auxiliary diagnostic information, combined with the preset interface layout principles for visual display, it can perform intelligent diagnosis, avoid adverse situations such as fatigue caused by frequent manual operations, and ensure the consistency of the diagnosis results, thereby improving the reliability of the diagnosis results.

[0065] In the embodiment of the present application, step 1, obtaining an original endoscope image and processing the original image according to a preset algorithm to obtain an enhanced image, may include the following:

[0066] Stretching the corresponding channel of the original endoscope image in the first color space, for example, stretching the grayscale contrast of the corresponding channel;

[0067] Converting the stretched first color space image to a second color space, and stretching corresponding channels in the second color space, for example, stretching the grayscale contrast of the corresponding channels;

[0068] The stretched second color space image is converted to the first color space to obtain an enhanced image.

[0069] Due to the interference of various factors, the contrast between organs and background in the original endoscopic image is low. In an embodiment of the present application, the original endoscopic image is stretched in the channels of the first color space and the second color space in sequence to enhance the contrast. Therefore, the noise interference of the image can be effectively reduced, and an image with better visual effect, i.e., an enhanced image, can be obtained to provide clear and reliable image data for the prevention, analysis and diagnosis of diseases.

[0070] Specifically, the corresponding channels of the original endoscope image are stretched in the first color space, wherein the first color space may be an RGB color space, and the mapping function for contrast stretching the green (G) channel in the RGB color space may be expressed by the following formula:

[0071] g * (x,y)=[1+d g ×((g(x,y)) -1 -1) 2 ] -1

[0072] In the above formula, g(x, y) and g * (x, y) are the normalized grayscale values ​​of the G channel of the original image and the enhanced image at the pixel point (x, y); d g It is the grayscale mapping parameter of G channel.

[0073] In addition, the contrast stretching amounts of the red (R) channel and the blue (B) channel may be adjusted or determined based on the green (G) channel, which is not limited here.

[0074] Specifically, the stretched first color space image is converted to the second color space, and the corresponding channel is stretched in the second color space, wherein the second color space may be an HSV color space, and the mapping function for stretching the grayscale contrast of the saturation (S) channel in the second color space can be expressed by the following formula:

[0075] s * =[1+d s ×(s -1 -1) 2 ] -1

[0076] In the above formula, s and s * are the grayscale values ​​of the S channel before and after mapping; d s It is the S channel grayscale mapping parameter.

[0077] In the embodiment of the present application, step 2, extracting the target organ image based on the enhanced image, may include the following:

[0078] Performing superpixel gridding processing on the enhanced image by a preset segmentation algorithm to obtain a plurality of superpixels, wherein the preset segmentation algorithm may be a SLIC superpixel segmentation algorithm;

[0079] Superpixels are classified based on convolutional neural networks to distinguish between superpixels inside organs and superpixels at the edges of organs;

[0080] Select several seed points of organ edge superpixels to construct the initial contour;

[0081] Based on the initial contour, the target organ image is segmented and extracted by solving the minimum value of the preset function.

[0082] Obviously, since the embodiment of the present application distinguishes between superpixels inside the organ and superpixels at the edge of the organ through a convolutional neural network, and constructs an initial contour by selecting seed points of several superpixels at the edge of the organ, and then segments the target organ image and extracts it by combining the initial contour with the solution of the minimum value of the preset function, it can reduce the sensitivity of the initial contour, reduce the segmentation time, improve the accuracy of the segmentation results, and thus ensure the integrity and accuracy of the extracted organs.

[0083] Specifically, superpixels are classified based on a convolutional neural network to distinguish between superpixels inside organs and superpixels at the edge of organs. The objective function of the convolutional neural network can be:

[0084]

[0085] In the above formula, represents the probability distribution of the pixel point x output by the soft-max layer of the convolutional neural network, i represents the number of layers of the convolutional neural network, λi is the weight factor of the i-th layer, N is the total number of pixels, Ni is the total number of pixels in a category Lm, k represents the basic fact category label, and k∈[0,1] represents the basic fact category label, where 0 represents the superpixel inside the organ, 1 represents the superpixel at the edge of the organ, and x is the pixel point.

[0086] In this embodiment, the convolutional neural network can be trained by a stochastic gradient descent method.

[0087] In the embodiment of the present application, step 3 is to detect the lesion area in the target organ image according to a preset recognition algorithm, and evaluate the lesion condition of the target organ based on the lesion area, which can be specifically:

[0088] Acquire several lesion images and extract the depth features of the lesion images one by one;

[0089] The deep features of each lesion image are encoded into multiple groups of integers through a hash algorithm and stored in a Bloom filter;

[0090] When receiving the image of the target organ to be detected, extracting the depth feature of the image of the target organ to be detected;

[0091] The deep features of the image of the organ to be detected are encoded using a local sensitive hash function. After encoding, a proximity search is performed in a Bloom filter to evaluate the pathological condition of the target organ based on the search results. For example, if no proximity is retrieved, it means that there is no lesion in the image of the target organ. If a proximity is retrieved, the lesion condition is output based on the approximate lesion image.

[0092] Obviously, since the depth features of several lesion images are encoded as integers and stored in the Bloom filter, when the target organ image needs to be detected, it is only necessary to encode the depth features of the target organ image using a local sensitive hash function and perform a proximity search in the Bloom filter. Therefore, the retrieval results can be output quickly, thereby not only reducing the latency but also having a very high throughput.

[0093] Specifically, the deep features of the image of the organ to be detected are encoded using a locality-sensitive hash function. After encoding, a proximity search is performed in the Bloom filter to evaluate the pathological condition of the target organ based on the search results. The locality-sensitive hash function h is a type of hash function that encodes a floating-point vector into an integer or Boolean vector, which can be expressed as follows:

[0094]

[0095] In the above formula, w is a randomly generated normalized vector, b is the offset of random sampling, and ε is a hyperparameter used to control the width of the encoding interval;

[0096] Obviously, since the local sensitive hash function is used to encode the deep features of the image of the organ to be detected, it is very easy to encode it into the same integer number, which makes it very convenient for retrieval, thereby improving computing efficiency and saving costs.

[0097] In the embodiment of the present application, step 4, combining the lesion condition as auxiliary diagnostic information with the target organ image, and performing a visual display in accordance with the preset interface layout principles, may include the following:

[0098] Based on the visual attention correlation principle and the objective operation principle, the interface layout principle is constructed and converted into a computable interface layout multi-objective optimization function;

[0099] The target optimization function is encoded through a preset algorithm to seek the optimal spatial solution, and then the optimal solution for the combined interface layout of auxiliary diagnostic information and target organ images is obtained, and a visual display is performed based on the optimal solution.

[0100] It can be seen that the embodiment of the present application combines the visual attention correlation principle and the objective operation principle to construct an interface layout principle, and converts the interface layout principle into a computable interface layout multi-objective optimization function, and then obtains the optimal solution for the interface layout by solving the target optimization function. Obviously, the visual display of auxiliary diagnostic information and target organ images based on the optimal solution can effectively enhance the visual effect and thus improve the user experience.

[0101] Based on the same inventive concept, the embodiment of the present application provides an endoscope display enhancement system, such as Figure 2 As shown, including:

[0102] Enhancement module 1 is used to obtain the original image of the endoscope and process the original image according to the preset algorithm to obtain the enhanced image, specifically:

[0108] The display module 4 is used to combine the pathological condition as auxiliary diagnosis information with the target organ image and perform visual display in accordance with the preset interface layout principle.

[0109] Obviously, the embodiment of the present application enhances the original endoscope image, thereby suppressing noise, weakening or removing certain unnecessary information, and highlighting the useful information in the image, thereby improving the visual effect of the endoscope image;

[0110] At the same time, since the diseased area in the target organ image is detected according to the preset recognition algorithm, and the diseased condition of the target organ is evaluated based on the diseased area, and the diseased condition is combined with the target organ image as auxiliary diagnostic information, combined with the preset interface layout principles for visual display, it can perform intelligent diagnosis, avoid adverse situations such as fatigue caused by frequent manual operations, and ensure the consistency of the diagnosis results, thereby improving the reliability of the diagnosis results.
