[0027] The present invention will be further described below in conjunction with the drawings.
[0028] Such as figure 1 Shown is a schematic diagram of the image recognition network structure. The image similarity calculation method based on the improved Soft-Max loss function of the present invention mainly includes the following steps:
[0029] Step (1): Prepare the image recognition training data set. The training data set is the open source image recognition database ImageNet 2012, including more than 1 million images in 1,000 categories. Input the image recognition training data set to the convolutional neural network Start training in the image recognition network. The image recognition network based on the convolutional neural network includes four network layers: convolutional layer, maximum sampling layer, fully connected layer, and improved Soft-Max layer. Among them, a convolutional layer and A maximum sampling layer constitutes an image recognition substructure. The ...
