1. A human re-identification method, comprising:
estimating positions of predefined joints of a human to be re-identified in an image of the human;
clipping from the image, along a body of the human, the same number of patches as the joints, each patch being centered on a corresponding joint, based on the positions of the joints;
generating positional information of each of the joints;
inputting the same number of patches as the joints with the positional information of the joints into a vision transformer encoder in a predetermined joint order;
inputting an output of the vision transformer encoder into a neural network; and
obtaining an output of the neural network as a re-identification result of the human.
