Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings.
[0042] refer to figure 1 , the concrete steps that the present invention realizes are as follows:
[0043] Step 1, get training samples.
[0044] Step 1, read in the registered SAR image;
[0045] Step 2: Carry out sliding window segmentation on the registered SAR image, the step size of the sliding window is 5, and obtain 7500 pairs of image blocks with a size of 28×28 with matching labels, among which 5000 pairs of image blocks will be randomly selected As training samples, the remaining 2500 pairs of image patches are used as testing samples.
[0046] Step 2, design and train a deep neural network.
[0047] Step 1, design a deep neural network with an input layer, two hidden layers and an output layer, the number of nodes in each layer is 1568, 784, 100, 1;
[0048] Step 2, input the training samples into the deep neural network;
[0049]The third step is to u...
