This paper proposes an improved level set segmentation algorithm based on skin color feature to implement accurate hand contour segmentation from clutter background.It introduces the deduction and implementation of the proposed total algorithm.When applying the improved algorithm to hand tracking,the location and size of hand obtained by particle filter is taken to initial the level set function,which can speed up the convergence speed of curve iteration.The extracting contour is used to locate fingertips.Experimental result shows that the algorithm can track accurate hand contour and fingertips from clutter background in real-time.
