[0035] Example
[0036] like figure 1 Shown is a flow chart of a pedestrian re-identification method based on label uncertainty and human component model. The specific steps include:
[0037] (1) Build a deep neural network model based on human components;
[0038] In the step (1), the ResNet-50 network is used as the basic structure to modify and adjust.
[0039] In this embodiment, a deep neural network model for 6 classification tasks based on human body components is constructed.
[0040] The deep neural network construction method is as follows: remove the fully connected layer with an output dimension of 1000 in the ResNet-50 network, and modify the downsampling rate stride=2 in layer4 to stride=1; after the pooling layer is divided into 6 Each part contains a fully connected layer of 256 neurons, a batch normalization layer, a dropout layer, and finally a classification fully connected layer.
[0041] (2) Initialize the constructed deep neural network model, and tra...
