Abstract

The embodiment of the invention discloses an image retrieval method and device, a graphic processor and a storage medium. According to the embodiment of the invention, The method includes acquiring the image feature information of the retrieved image and the pre-stored image can be acquired, and calculating the similarity between the pre-stored image and the retrieved image is calculated accordingto the image feature information; S; sampling the pre-stored image to obtain a sample image, and determining a similarity threshold value according to the similarity of the sample image; S; sequencing the pre-stored images of which the similarity values are greater than a similarity threshold value to obtain a candidate image sequence; and selecting a target image from the candidate image sequence. Therefore, according to the scheme, the pre-stored images are screened, the sorting work is reduced, the high-quality retrieval result can be obtained only by partially sorting the pre-stored images, the image retrieval time is shortened, resource occupation is reduced, and the image retrieval efficiency is effectively improved.

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...
