Video object plane extraction for surveillance applications
Juan Li, Xianmin Zhang · 2005
Extraction of video object plane (VOP) is the central challenge for content-based video processing. It enables separate and flexible manipulation, blending and arrangement of content at MPEG-4 based decoder. We present a fast and efficient extraction algorithm depending on edge detection. Our algorithm begins with finding edge candidates detected by Canny edge detector. After selecting edge pixels which belong to the moving object in current frame, the VOP is extracted by using morphological operations. The proposed algorithm is evaluated on MPEG-4 test sequence and generates desirable VOPs at a lower computation cost.
