Analysis of contour evolution methods for segmentation of medical images

Deformable models are promising and robustly researched computer-assisted medical image analysis technique. Here the segmentation is done by using the contour evolution method. The control points are automatically placed by thresholding and then the contour is applied to segment the particular area. The contour is applied for four prior models to segment the heart. Among the various prior models, shape is the most important to acquire the heart shape accurately. This approach is used to segment the heart from the computed tomographic image. Finally the analysis is performed by comparing the result with other deformable models.
