Embodiment 1

[0024] figure 1 This is a schematic flowchart of an image comparison method provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation of searching for relatively similar images from a large number of images. The method can be executed by an image comparison device, which can It is implemented by means of software and / or hardware, and the apparatus can be integrated into a computing device, and can also be used as an independent device. Specifically include the following steps:

[0025] S110. Determine a luminance histogram and / or a chromaticity histogram of each image to be compared according to the luminance value and / or chromaticity value of the image to be compared.

[0026] In this embodiment, the above-mentioned images to be compared are images that need to be compared for similarity, wherein the images to be compared may be two images to be compared with an existing image found from a large number of images Compare images. The ...

Embodiment 2

[0047] image 3 It is a schematic flowchart of an image comparison method provided in Embodiment 2 of the present invention. On the basis of Embodiment 1 above, this embodiment further determines the brightness value and / or chromaticity value of the image to be compared. The luminance histogram and / or the chrominance histogram of the images to be compared are explained in detail. see image 3 , the method can specifically include:

[0048] S310: Determine a preset gray scale range according to the actual comparison speed of the images to be compared.

[0049] In this embodiment, the comparison process of the images to be compared is processed on the corresponding equipment. When the processing speed of the equipment is different, in order to achieve fast image comparison, the gray scale range of the images to be compared can be adjusted. . Exemplarily, when it is planned to achieve a comparison speed of 1000 images per second on the device, two channels of contrast luminan...

Embodiment 3

[0061] Figure 4 This is a schematic structural diagram of an image comparison apparatus provided in Embodiment 3 of the present invention. The apparatus can execute the image comparison method provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method. like Figure 4 As shown, the apparatus may include:

[0062] A histogram determination module 401, configured to determine the luminance histogram and / or the chromaticity histogram of each image to be compared according to the luminance value and / or the chromaticity value of the image to be compared;

[0063] The similarity determination module 402 is configured to determine the similarity between the images to be compared according to the luminance histogram and / or the chromaticity histogram of the images to be compared.

[0064] Further, the device also includes:

[0065] Integrity detection module 403, configured to detect the integrity of ...

Abstract

The embodiment of the invention discloses an image comparison method, device, equipment and storage medium. The method includes: determining the brightness histogram and / or chromaticity histogram of each image to be compared according to the brightness value and / or chromaticity value of the image to be compared; or chromaticity histogram to determine the similarity between the images to be compared, not only can quickly search for similar images, but also the implementation process is simple and efficient.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image comparison method, apparatus, device, and storage medium. Background technique [0002] With the advancement of science and technology, image comparison technology has been paid more and more attention by the public. [0003] One of the existing image comparison techniques is to segment the image and compare the segmented images, and the other is to extract the image feature values ​​in the compared images, such as color, texture, shape, contrast, vector and other features. , and then determine whether different images are the same image through the comparison of these features. [0004] Therefore, in the existing technical solution, the process of comparing different images is relatively long, which is cumbersome to implement, and it is difficult to realize massive image comparison. SUMMARY OF THE INVENTION [0005] The embodiment...
