Algorithm 1.

Partial Salient Contour Detection

- Get all the salient contour points whose NVP contrast c is smaller than −1.
- Estimate the intensity distribution of the prostate according to the shape initialization.
- Compute the mean value of NVPs. If the value is smaller than the lower boundary of the prostate’s intensity range, remove the point from the salient point set, since this is likely to be in shadow area.
- Apply ID median filter to the point list and remove isolated points, which are often caused by noise.
