Abstract

A reference frame was selected from a video sequence, and corners were found by Harris operator. Corners were tracked by Lucas-Kanade optical flow which was based on Gaussian Pyramid, like this those corners were traced in the current frame. Then corresponding corner set between the reference frame and the current frame were obtained. An affine transformation matrix can be solved by those two corner sets above. Stabilized video sequence was got by affine transformation of current frame.
