[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.
[0025] Such as figure 1 Shown is a flow chart of the present invention, comprising the following steps:
[0026] Step 1: Divide the image set to be classified into training sets {A i} dataset.
[0027] Step 2: Select a deep neural network model, you can choose a deep convolutional neural network model;
[0028] Step 3: Write the local feature output layer of the deep neural network model as a matrix Each row i∈[1,c] represents a feature map, each column j∈[1,hw] represents a spatial position, c is the number of channels of the feature map, h is the height of the feature map, and w is the width of the feature map ;
[0029] make is the singular value decomposition of matrix X, where u i is the left singular vector of matrix X, v i is the right singular vector of matrix X, σ i i...
