| 摘要 | A video processing method includes the steps of: inputting a video; matching multiple frames of the video according to corresponding positions, wherein one of the frames serves as a reference image; marking a motion region, to be preserved, in the video; and submerging a content of each of the frames, corresponding to the motion region, into the reference image to generate a replacement frame. An electronic device is also disclosed. | ||

| 主权项 | 1. A video processing method, comprising the steps of: inputting a video; matching multiple frames of the video according to corresponding positions, wherein one of the frames serves as a reference image, wherein the step of matching the frames of the video according to the corresponding positions comprises: checking at least one characteristic corner in a first frame of the frames;calculating an error amount between the characteristic corner and each of corresponding candidate points in a second frame of the frames when one of the characteristic corners is checked;finding a minimum error from the error amounts;setting the characteristic corner and the corresponding candidate point, corresponding to the minimum error, as matching corners;calculating corner offsets on coordinate values of the matching corners in the first frame and the second frame; andcalculating an overall offset according to the corner offsets; marking a motion region, to be preserved, in the video; and submerging a content of each of the frames, corresponding to the motion region, into the reference image to generate a replacement frame, wherein the step of submerging the content of each of the frames, corresponding to the motion region, into the reference image to generate the replacement frame comprises: finely tuning coordinates of the frames corresponding to the motion region according to the overall offsets, respectively; andsubmerging a content of each of the frames, corresponding to the motion region after fine tuning, into the reference image to generate the replacement frame. | ||
