摘　　要：本论文的研究对象是古旧电影胶片中的动态图像。将嵌入线性划痕噪声的动态胶片图像进行数字化处理后高速检索、修复。算法沿用传统的块匹配技术,并在其基础上做了改进,即采用平均位移量手段来推断对象象素的位移量、同时修正检索中心的位置,以达到精准快速的处理效果。这种处理方式在实验中得到了验证,在没有降低噪声修复质量的前提下提高了处理速度,基本实现了实时处理。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.
