Problems solved by technology

For targets with standard shapes or standard outlines, such as faces, cars, and pedestrians, the target detection results of this method are relatively accurate; but for targets with variable shapes or large differences in outlines, such as debris piles and accumulations of various objects etc. A large amount of background information will be introduced when the target is detected through the rectangular frame, which will interfere with the target detection and affect the accuracy of target detection.

Embodiment 1

[0032] First, refer to figure 1 An example electronic system 100 for implementing the object detection method, device and electronic system of the embodiments of the present invention will be described.

[0033] Such as figure 1 A schematic structural diagram of an electronic system is shown, the electronic system 100 includes one or more processing devices 102, one or more storage devices 104, input devices 106, output devices 108, and may also include one or more image acquisition devices 110 , these components are interconnected via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.

[0034] The processing device 102 may be a gateway, or an intelligent terminal, or a device including a central processing unit (CPU) or other forms of pr...

Embodiment 2

[0041] Embodiments of the present invention provide a target detection method, such as figure 2 As shown, the method includes the following steps:

[0042] Step S202, extracting image features of the image to be processed;

[0043] The image to be processed above usually refers to the image to be detected, which can be an image containing objects with variable shapes, large contour differences, or irregular shapes, such as debris piles (garbage piles, express piles, etc.), various Images of objects such as accumulations of objects (scattered piles of toys, books, etc.), irregularly placed objects (disorderly bicycles, etc.). The above-mentioned image features may refer to the high-dimensional feature data of the image to be processed, which usually includes detailed features of the image to be processed; specifically, the image to be processed (also called the original image) may be input to the feature extraction network, and the image to be processed is output. Process th...

Embodiment 3

[0053] The embodiment of the present invention also provides another target detection method, which is implemented on the basis of the above embodiments; this embodiment focuses on the specific steps of determining the image region containing the target object in the image to be processed based on image features Implementation mode (realized by steps S304-S306); as image 3 As shown, the method includes the following steps:

[0054] Step S302, extracting image features of the image to be processed;

[0055] Step S304, input the image features into the pre-trained area segmentation network, and output the area mask image; wherein, in the area mask image, the pixel value of the pixel position within the image area is the first pixel value; The pixel value of the pixel position outside is the second pixel value;

[0056] The above-mentioned pre-trained region segmentation network can identify the position information of the image region in the image feature, and the edge shape ...

Abstract

The invention provides a target detection method and device and an electronic system. The method comprises the following steps: extracting image features of a to-be-processed image; based on the image features, determining an image region containing a target object in the to-be-processed image, wherein the edge shape of the image area is related to the edge shape of the target object, and the area occupied by the target object is smaller than the image area; performing feature enhancement processing on region features corresponding to the image region in the image features to obtain processed image features; and detecting a target object based on the processed image features. The method can be understood that the target object is roughly segmented in advance to obtain an image area containing the target object; feature enhancement processing is carried out on region features corresponding to the image region in the image features; according to the method, the object features of the target object can be enhanced, the features of the background area in the image are further weakened, interference of background information in the target detection process is reduced, and the target detection accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a target detection method, device and electronic system. Background technique [0002] In related technologies, the target detection task usually uses a rectangular frame to locate the target, and then recognizes the category of the target in the rectangular frame. For targets with standard shapes or standard outlines such as faces, cars, and pedestrians, the target detection results of this method are relatively accurate; but for targets with variable shapes or large differences in outlines, such as debris piles and accumulations of various objects etc. A large amount of background information will be introduced when the target is detected through the rectangular frame, which will interfere with the target detection and affect the accuracy of target detection. Contents of the invention [0003] In view of this, the object of the present invention is to provid...
