This algorithm traces the prostate boundary from the target image, non prostate binary mask image and prostate boundary binary mask image. After AAM generates the initial contour, the contour is copied to all the three images. Target image represent the test image original intensity texture. non-prostate binary image and prostate boundary image are generated from SVM classification. Current tracing mechanism is polar coordinate based, along the AAM generated initial contour landmark points, the alpha angel ranges from 0 to 360 degree, the alpha expansion line is used for tracing the ideal prostate boundary point. A basic voting mechanism is applied to find the ideal point. Lately, we will use normal line of the contour curve from the landmark point to represent the tracing path.
