A fast and automatic video object segmentation algorithm based on wavelet transform and moving edge detection is proposed in this paper. First, the wavelet transform is applied to two consecutive frames. The change detection method with different thresholds in four wavelet sub-bands and Canny edge detection are used in wavelet domain. After the inverse wavelet transform, the robust difference edge...
This paper presents an adaptive immune genetic algorithm (AIGA) for image segmentation based on the cost minimization technique. The image segmentation problem is treated as one of combinatorial optimization. A cost function which incorporates both edge information and region gray-scale uniformity is used. The immune genetic algorithm is treated as an optimization technique to find the optimal solution...
