Abstract

The embodiment of the invention discloses an image retrieval method, device, graphics processor and storage medium. The embodiment of the present invention can obtain the image feature information of the retrieved image and the pre-stored image, calculate the similarity between the pre-stored image and the retrieved image according to the image feature information; sample the pre-stored image to obtain a sample image, and determine the similarity according to the similarity of the sample image Threshold; sort the pre-stored images whose similarity value is greater than the similarity threshold to obtain a candidate image sequence; select the target image from the candidate image sequence. Therefore, the scheme screens the pre-stored images, reduces the sorting work, and only needs to partially sort the pre-stored images to obtain high-quality retrieval results, shortens the time of image retrieval, reduces resource occupation, and effectively improves the efficiency of image retrieval .

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an image retrieval method, device, graphics processor and storage medium. Background technique [0002] With the development of Internet technology, image retrieval has become a widely used retrieval method, such as landscape retrieval, face retrieval and / or vehicle retrieval and so on. At present, image retrieval on general-purpose image processors mainly uses CUBLAS (Compute Unified Basic Linear Algebra Subprograms, Unified Computing Basic Linear Algebra Subprograms Library) to perform feature matching between the reference image to be retrieved and a large number of images to be selected in the database. Calculate, and completely sort the massive candidate images according to the feature matching degree, and select the preset number of candidate images in the image sequence as the retrieval results after sorting. [0003] During the research and practice of the prior a...
