Embodiment 1
[0040] Embodiment 1: as figure 1 As shown, a pedestrian re-identification method based on label consistency constraints and stretched regularized dictionary learning, the specific steps of the pedestrian re-identification method based on label consistency constraints and stretched regularized dictionary learning are as follows:
[0041] Step1. Construct training samples and test samples of feature data from two perspectives;
[0042] The concrete steps of described step Step1 are as follows:
[0043] Step1.1. Extract LOMO features from the pictures on the public dataset;
[0044] Step1.2, and then reduce the dimensionality of the feature data, the data of each picture after dimensionality reduction is a column vector (n×1), as a sample of a pedestrian under one viewing angle; the sample data of all pedestrians under one viewing angle is the feature matrix (n×m), n is the dimension of the feature, and m is the number of pedestrians;
[0045] Step1.3. Obtain the feature matri...
Embodiment 2
[0068] Embodiment 2: as figure 1 As shown, a pedestrian re-identification method based on label consistency constraints and stretched regularized dictionary learning, the specific steps of the pedestrian re-identification method based on label consistency constraints and stretched regularized dictionary learning are as follows:
[0069] Step1. Construct training samples and test samples of feature data from two perspectives;
[0070] The concrete steps of described step Step1 are as follows:
[0071] Step1.1. Randomly select 316 pedestrians from the pictures on the public VIPeR dataset to be divided into a training set, and the remaining 316 pedestrians are used as a test set for LOMO feature extraction; figure 2 Pedestrian images under two perspectives randomly extracted from the public dataset VIPeR commonly used for pedestrian re-identification in the present invention, the upper column is the pedestrian image of the a perspective, and the next column is the pedestrian im...
