IMAGE RETRIEVAL METHOD AND SYSTEM, AND DEVICE AND MEDIUM

Disclosed is an image retrieval method, comprising: constructing an image training set and a weight-shared Siamese network; calculating a correlation between every two images in the image training set; inputting different images in the image training set into the Siamese network, so as to obtain a first encoded vector and a second encoded vector; calculating a loss function according to the first encoded vector, the second encoded vector, and the correlation between two images that are currently input into the Siamese network, so as to train the Siamese network according to the loss function and compare same with a preset requirement; and in response to the Siamese network, which has been trained several times, meeting the preset requirement, performing image retrieval by using a single network structure in the trained Siamese network. Further disclosed are a system, a computer device and a readable storage medium. Est divulgué un procédé de récupération d'image, comprenant : la construction d'un ensemble d'e
