The problem of object contour tracking in image sequences remains challenging, especially those with cluttered backgrounds. In this paper, the fast two-cycle level set method with narrow perception of background (FTCNB) is proposed to extract the foreground objects, e.g. vehicles from road image sequences. The curve evolution of the level set method is implemented by computing the signs of region...
The problem of tracking foreground objects in a video sequence with moving background remains challenging. In this paper, we propose the Fast Two-Cycle level set method with Narrow band Background (FTCNB) to automatically extract the foreground objects in such video sequences. The level set curve evolution process consists of two successive cycles: one cycle for data dependent term and a second cycle...
