摘要
A method and system for sensing disappearance of the previously detected logos in noisy digital video signals. When a video program starts, a short period of time is allowed to initially detect the existence and the location of the logo within the incoming video frames. Once the logo is detected and a logo map is generated, logo tracking senses whether the logo remains in, or disappears from, the video frames. If the logo moves or (partially) changes its intensity, color, pattern, etc., it will be sensed as having disappeared altogether.
