Abstract

The invention provides a method and device for evaluating robustness of a similar image retrieval algorithm, wherein the method comprises: retrieving in a test data set for each image to be retrieved according to the similar image retrieval algorithm, and setting a corresponding retrieval integral for each image to be retrieved according to the retrieval results; determining a corresponding original average integral to the similar image retrieval algorithm based on the corresponding retrieval integral of each image to be retrieved; reducing quality of each sample in at least two test arrays; retrieving again in the test data set according to the similar image retrieval algorithm so as to obtain a corresponding actual average integral of the similar image retrieval algorithm at the premise of image processing; determining factors affecting the robustness of the similar image retrieval algorithm based on the original average integral and the actual average integral. The method and device according to the technical scheme provided herein enable factors affecting the robustness of the similar image retrieval algorithm to be determined.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image retrieval, in particular to a robustness evaluation method and device for a similar image retrieval algorithm. Background technique [0002] At present, image recognition technology has been applied to face recognition in the field of security, vehicle retrieval in the field of intelligent transportation, etc. Similar image retrieval algorithms usually include three main functions: feature extraction, feature similarity calculation, and similarity ranking. The algorithm extracts the feature of the image to be retrieved, and calculates the similarity with each feature value in the feature database, so that the picture with the highest similarity can be returned. Ideally, the image with the highest similarity in similarity ranking is the target image. The images to be retrieved obtained in the real scene are affected by external conditions, such as changes in lighting condi...
