For various video-related applications, high-efficiency scalable video coding and foreground visual object representation are two of the most importantenabling technologies. On one hand, with the exponentially increasing usage of video teleconferencing and real-time traffic monitoring, the high-bit-rate video streams are often required to be real-timely and simultaneously coded or transcoded into multiple quality-maintained low-bit-rate videos for the various bandwidths of client devices. On the other hand, it is crucial to represe
