The invention discloses an image recognition method and device, a pedestrian re-recognition method and device, and electronic and storage equipment. The image recognition method comprises the steps: obtaining the image features of a frame image in an image sequence; determining sub-features of the image features and attribute groups corresponding to the sub-features according to the image featuresof the frame image; according to the attribute group corresponding to the sub-feature, determining a time sequence weight of the sub-feature; determining fusion features of the sub-features corresponding to the same attribute group according to the time sequence weight; determining features of the image sequence according to the fusion features and global features of the image sequence; and performing re-identification retrieval according to the characteristics of the image sequence. The problems of inconsistent information amount and the like caused by quality change, shielding and the likeof the image sequence can be solved, the obtained characteristics of the image sequence have stronger expression ability, and the matching accuracy is improved during retrieval.
Description
technical field [0001] This application relates to the field of computer vision, in particular to an image recognition method and device. The present application also relates to a pedestrian re-identification method and device. The present application relates to an electronic device and a storage device at the same time. Background technique [0002] Person Re-Identification (Person Re-Identification) can also be called image re-identification, which has a wide range of applications in the fields of transportation and security. Pedestrian re-identification is to extract the features of the people appearing in the surveillance video, search for images similar to the query image in the bottom database, and obtain the trajectory information of the image across cameras to complete the search for key people. [0003] In the prior art, when re-identifying an image, usually by inputting a query image of an image, searching for other images of the same person in the bottom library...
