Example Embodiment
[0025] The preferred embodiments of the present invention are detailed as follows with reference to the drawings:
[0026] The structure of the multi-column convolutional neural network of this embodiment is as follows figure 1 Shown. In Ubuntu 16.04, PyTorch environment programming simulation to achieve this method. First, design a multi-column convolutional neural network model according to the deep learning algorithm, including feature extraction part and image reconstruction part. Then, the original image is cut into small blocks, and these high-resolution small blocks are down-sampled to obtain low-resolution small blocks, and these low-resolution and high-resolution small block pairs are used to build a training set. Finally, the stochastic gradient descent algorithm is used to train this model to obtain a model that reconstructs a low-resolution image to a high-resolution image, that is, the image super-resolution reconstruction model of the multi-column convolutional neu...
