We introduce our efficient instance matting framework guided by instance binary masks, structured into two parts. The first Sec. 3.1 details our novel architecture to maintain accuracy and efficiency. The second Sec. 3.2 describes our approach for ensuring temporal consistency across frames in video processing.
