SYSTEM AND METHOD FOR ELECTRONIC IMAGE STABILIZATION |
摘要 |
The invention is a system and method for electronic stabilization of an image produced by an electronic imaging device. The input may be any sequence of image frames from an image source, such as a video camera, an IR or X-ray imager, radar, or from a storage medium such as computer disk memory, video tape or a computer graphics generator. The invention can also be used with images from multiple sources when these must be stabilized with respect to one another. The invention uses a feedback loop (104) and second image warp stage (116) to achieve precise image alignment as part of the displacement estimation process. The output of the stabilization system is a modified image sequence in which unwanted components of image motion have been reduced or removed, or in which new motion of a desired form has been introduced. The output may also include information derived from the input sequence, such as estimated frame-to-frame displacement vectors or motion flow fields, and derived image sequences with reduced noise or highlighted change. |
