UAV Motion-Blurred Image Restoration Using Improved Continuous Hopfield Network Image Restoration Algorithm

The performance of blind detection algorithm based on Hopfield neural network depends on the choice of activation function. According to this principle, we change the activation function of continuous Hopfield image restoration algorithm to improve the performance. Compared with the previous algorithm, the improved algorithm greatly speeds up the convergence rate without reducing the quality of the repaired image. The new algorithm can resolve unmanned aerial vehicle (UAV) motion-blurred image restoration, combining with the estimated point spread function (PSF). The experimental results show the superiority of the new algorithm.
