A Novel Algorithm Based on Contourlet Transform for Medical Image Segmentation
In this paper, a novel algorithm in the contourletdomain is presented for segmenting lumbar vertebra in Ctimage. Firstly we apply the contourlet transform to the image,use its multiscale and multidirectional characteristics to get thecoefficients that they can effectively capture the contours of animage and depict them sparsely. Secondly, C-Means clusteringalgorithm is applied to derive the edge information from thecontourlet coefficients. Experimental results are encouraging,which illustrate the effectiveness of the algorithm. Comparedwith the wavelet-based method, our algorithm can get asatisfactory results.
