A new video inpainting method based on three-dimensional Poisson equation was presented. The gradient fields of video frame were extracted first. Then, the target areas of every gradient fields were filled in the patch-by-patch inpainting methods. Afterwards, to repair the video, a three-dimensional Poisson equation was built and solved in the gradient field of the target area. Experiment results have shown that the proposed method can achieve the desired results and perform better than the existing methods in color, light and shade consistency.
