The Study of High-speed Denoising Algorithm for Motion Images in Films
电影胶片动态图像高速去噪算法研究

The object of the study is the motion images in the old films. After digitization, the motion images with dynamic noise and linear scratches were retrieved and repaired in high-speed. Based on the traditional block matching technology, the algorithm has been improved. Which means to achieve the fast and accurate treatment effect, the average displacement algorithm has been chosen to infer the object＇s pixel displacement, amend the position of retrieve center. The experiment results show that the approach has improved the processing speed, basically realized real-time processing,without reducing the noise repair quality.
