  • IMAGE SEARCH METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
    Publication number: 20210397645
    Abstract: An image search method is provided. In the method, an image selection page of a messaging application is displayed. An input image for a search is determined based on an operation performed by a user on the image selection page. A search is performed for at least one output image similar to the input image based on a plurality of types of image characteristics that indicate levels of similarity between images. Each of the ay least one output image is determined to be similar to the input image based on at least one of the types of image characteristics. A search result list is generated according to the at least one output image. Further, the search result list is displayed.
