INTRODUCTION (2) Active Contour Models- Snakes: The developers of Active Contours, or Snakes are Kass, Witkin and Terzopoulous. The name reveals from motion of contour. The active contour model or snake is an energy minimizing spline and its energy depends either on its shape and location within the object. Active contour models are used in image segmentation and local minima of this energy depends on desired image properties. To be able to match a deformable model to an image by the use of energy minimization the most general technique that we can use is snake algorithm. Snake algorithm by itself is not sufficient to converge the contours in images. They totally based on interaction with some high level image understanding process or information from image data in time or space. This interaction should define a close shape and also define the initial starting point. Whatever you are getting closer initial point near the desired contour you have faster converging time.
