Aiming at the problem that the traditional image restoration method is dependent on the prior knowledge of degenerated image, a new image restoration method based on hybrid neural network is proposed. The hybrid neural network is composed of Convolutional Neural Network(CNN)and BP network. Firstly, the preliminary nonlinear mapping relationship between degenerated image and clear image is established by training CNN. After then, the trained convolutional neural network model is utilized to extract feature v...
