Problems solved by technology
Traditional image feature descriptors cannot be stably obtained in images that are considered to be the same or basically the same in human vision, and the operation of image feature descriptors is too complicated, and the extracted image feature information is relatively difficult when used for retrieval. The matching effect is poor for images with many color levels and complex structures

Embodiment Construction
[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0030] The traditional image feature descriptors have poor matching effect in the retrieval of the same or similar images, and to a certain extent, there are the following limitations or defects: the stability of the common feature description of the same or similar images is insufficient, and the traditional image feature description The image descriptor cannot make the same or basically the same image in the human vision stable to obtain a consistent image feature descriptor, resulting in the missed detection of the same or similar image in image retrieval; the traditiona...

The present application relates to an image retrieval method, device, computer equipment and storage medium. The method includes: extracting image feature descriptors of sample images, and establishing a sample image database; acquiring an input image, and extracting image feature descriptors of the input images; the image feature descriptors include: feature descriptors of coordinate position relationships of image feature elements , the feature descriptor of the linear relationship of the image feature element, the feature descriptor of the angle relationship of the image feature element, the feature descriptor of other types of quantitative relationship of the image feature element; the image feature descriptor of the input image is used as the search term, in A sample image matching the image feature descriptor is retrieved from the sample image database, and the matched sample image is used as a result of the image retrieval. It can stably obtain consistent image feature descriptors; it can also enrich the types of image retrieval and effectively enhance the matching effect of images.
Description
technical field [0001] The present application relates to the technical field of image recognition and retrieval, in particular to an image retrieval method, device, computer equipment and storage medium. Background technique [0002] With the development of image processing technology, how to better describe image features has been the object of research in the field of image recognition and retrieval. A good set of image feature descriptors should have distinction and commonality. Distinction means that the descriptor can reflect the feature points that distinguish one image from another, making the descriptor unique to the image. . Commonality means that an image feature descriptor can reflect an image and other identical or similar images with the same feature points, so that the descriptor has common feature points for the same or similar images, so as to achieve the same or similar images. Good checkpoint match. [0003] Traditional retrieval techniques for the same...
