Mean-shift is an effective statistical iterative algorithm. In the iterative process, size of bandwidth has great impact on the accuracy and efficiency of the algorithm. It not only decides the number of sampling points in the iteration, but also affects the convergence speed and accuracy of the algorithm. So, the choice of bandwidth is very important. In this paper, bandwidth is calculated by using...
Mean shift, like other gradient ascent optimization methods, is susceptible to local maxima, and hence often fails to find the desired global maximum. For this reason, mean shift segmentation algorithm based on bacterial colony chemotaxis (BCC) is proposed in this paper. The mean shift vector is firstly optimized using BCC algorithm. Then, the optimal mean shift vector is updated using mean shift...
The human brain anatomy is extremely variable across individuals in terms of its size, shape, and structure patterning. In this paper, a novel method is proposed for grouping brain MR images into different patterns. This method adopts the affinity propagation methodology to partition a population of brain images into different clusters. In the affinity propagation method, the tissue-segmented and...
