The invention relates to a target similarity identification method, apparatus and device, a target stay time recording method, apparatus and device, a computer device and a storage medium. The targetsimilarity identification method comprises the steps of obtaining image data corresponding to targets in two groups of frame images, and obtaining feature point information of the targets in the imagedata, thereby obtaining a first feature point set and a second feature point set; according to the information of the feature point sets, obtaining a bidirectional similar distance between the firstfeature point set and the second feature point set, wherein the bidirectional similar distance is information for measuring a maximum mismatching degree between the first feature point set and the second feature point set; and according to the bidirectional similar distance, determining the similarity between the identified targets in the two groups of the frame images. According to the method, the similarity between the targets in the two groups of the images can be simply and efficiently extracted and compared, so that the identification efficiency of the target similarity is improved.
Description
technical field [0001] The present invention relates to the technical field of image recognition, in particular to a target similarity recognition method, a target residence time recording method, a device, a device, a computer device and a storage medium. Background technique [0002] Image recognition refers to the technology of using computers to analyze and process images to identify objects in the images. For example, the target in the image can be identified by extracting specific target features such as people, cars, and airplanes in the image. [0003] In the field of image recognition technology, the recognition and classification of similar objects is of great significance. For example, when multiple people appear in an image, high-precision recognition operations are required to effectively distinguish similar people. For the recognition of similar objects, a The important method is to calculate the similarity between objects in the image. [0004] Existing targ...
