Embodiment
[0042] This embodiment provides an unsupervised person re-identification method based on a self-label refined deep learning model, such as Figure 1 to Figure 3 As shown, the method includes the steps:
[0043] S1: Get a dataset of pedestrian images without labels where N is the number of pictures in the dataset, x i Represents the i-th pedestrian image in the dataset, adjust the size of each image to the same height and width, and perform preprocessing;
[0044] S2: Build a self-label refined deep learning model, input the preprocessed training data into the network, and extract the multi-granularity features of the picture samples; wherein, the multi-granularity features include global features, upper body features and lower body features;
[0045] S3: Cluster the extracted multi-granularity features to obtain global pseudo-labels, upper-body pseudo-labels and lower-body pseudo-labels;
[0046] S4: Build a memory module according to the clustering result, calculate the c...
