Embodiment Construction
[0021] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0022] Step 1. Construct the FCN network structure
[0023] The FCN network structure is composed of thirteen convolutional layers, five pooling layers and two deconvolutional layers. In this model, it is tuned on the VGG-16 model pre-trained by ImageNet. Remove the fully connected layer in the VGG-16 model, and add two layers of bilinear difference layer as the deconvolution layer. The first deconvolution layer performs 4-fold interpolation, and the second deconvolution layer performs 8-fold interpolation to expand the network output to the same size as the original image; set the classification category to two, for each pixel points for binary classification.
[0024] Step 2. Training network structure
[0025] Send the training samples to the network to classify each pixel in the image according to the output of the logistic regression classifier, use the s...
