VIDEO IMAGE STABILIZATION AND REGISTRATION

摘要

A method of stabilizing and registering a video image in multiple video fiel ds of a video sequence provides accurate determination of the image change in magnification (70), rotation (80) and translation (90) between video fields, so that the video fields may be accurately corrected for these changes in th e image in the video sequence. In a described embodiment, a key area of a key video field is selected which contains an image which it is desired to stabilize in a video sequence. The key area is subdivided (30) into nested pixel blocks and the translation of each of the pixel blocks (60) from the k ey video field to a new video field is determined as a precursor to determining change in magnification, rotation and translation of the image from the key video field to the new video field.
