Embodiment 1

[0024] figure 1 It is a schematic flow chart of an image comparison method provided in the first embodiment of the present invention. This embodiment can be applied to the situation of finding a relatively similar image from a large number of images. The method can be executed by an image comparison device, which can Implemented by software and / or hardware, the device can be integrated into a computing device or can be used as a stand-alone device. It includes the following steps:

[0025] S110: Determine 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.

[0026] In this embodiment, the above-mentioned image to be compared is an image that needs to be compared for similarity, where the image to be compared may be two images to be compared with an existing image from a large number of images. Compare images. The above-mentioned histogram (Histogram), also know...

Embodiment 2

[0047] image 3 It is a schematic flowchart of an image comparison method provided in the second embodiment of the present invention. This embodiment, on the basis of the above-mentioned embodiment 1, further determines each image according to the brightness value and / or chromaticity value of the image to be compared. The luminance histogram and / or chromaticity histogram of the image to be compared are explained in detail. See image 3 , The method may specifically include:

[0048] S310: Determine a preset grayscale range according to the actual comparison speed of the image to be compared.

[0049] In this embodiment, the comparison process of the image to be compared is processed on the corresponding device. When the processing speed of the device is different, in order to achieve rapid image comparison, the grayscale range of the image to be compared can be adjusted . Exemplarily, when a comparison speed of 1000 images per second is planned to be achieved on the device, two c...

Embodiment 3

[0061] Figure 4 This is a schematic structural diagram of an image comparison device provided in the third embodiment of the present invention. The device can execute the image comparison method provided by any embodiment of the present invention, and has corresponding functional modules and beneficial effects for the execution method. Such as Figure 4 As shown, the device may include:

[0062] The histogram determining module 401 is configured to determine the brightness histogram and / or the chromaticity histogram of each image to be compared according to the brightness value and / or 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 brightness histogram and / or the chroma histogram of the images to be compared.

[0064] Further, the device further includes:

[0065] The integrity detection module 403 is configured to detect the integrity of the i...

Abstract

The embodiment of the invention discloses an image comparison method and a device, equipment and a storage medium. The method comprises the steps of determining a brightness histogram and / or a chrominance histogram of each to-be-compared image according to brightness values and / or chrominance values of the to-be-compared images; and according to the brightness histogram and / or chrominance histogram of the to-be-compared image, determining the similarity between the to-be-compared images, so that not only can similar images be quickly searched, but also the implementation process is simple andefficient.

Description

Technical field [0001] The embodiments of the present invention relate to the field of image processing technology, and in particular, to an image comparison method, device, device, and storage medium. Background technique [0002] With the advancement of science and technology, image comparison technology has attracted more and more attention from the public. [0003] One of the existing image comparison technologies is to segment the image and compare the segmented images, and the other is to extract the image feature values ​​in the compared image, such as color, texture, shape, contrast, vector and other features , And then through the comparison of these features to determine whether the different images are the same image. [0004] Therefore, in the existing technical solutions, the comparison process between different images is relatively long, which is more complicated to implement, and it is difficult to achieve mass image comparison. Summary of the invention [0005] The e...
