[0056] figure 1 It is a flowchart of a super-resolution algorithm for fusion based on a convolutional neural network proposed by the present invention. In the figure, k represents the size of the convolution kernel, n represents the number of feature maps, and p represents boundary expansion. The purpose is to ensure that the size of the image before and after the convolution operation remains unchanged, and the step size of each convolution step is set to 1. The network proposed by the present invention can be divided into three parts, joint strategy, feature extraction and deep fusion. This part of the joint strategy is to generate the primary high-resolution image through the bicubic interpolation and FSRCNN of the low-resolution image, and then use the three convolutional layers of the feature extraction part to perform feature extraction. In the final depth fusion part, the The previously extracted features are fused with a 20-layer deep convolutional neural network to o...
