Edge detection is a fundamental tool in image processing, image pattern recognition, and computer vision techniques. Ideally, the result of applying an edge detector to an image should lead to a set of curves that indicate the contour of objects as well as curves that correspond to discontinuities in surface orientation. Furthermore, applying an edge detection algorithm to an image may reduce the amount of data to be processed while preserving the structural properties of an image. Edge detection is not a trivial task. There are many methods for edge detection. In this paper, we will introduce the active contour method, or snake algorithm, which minimizes the energy function. Active contours have multiple advantages over classical feature attraction techniques. Snakes are easy to manipulate using external image forces. They are self-adapting in their search for a minimal energy state. Furthermore they can be used to track dynamic objects in temporal as well as the spatial dimensions. Nevertheless, one of the biggest drawbacks of this method is that snakes are get stuck in local minima states.
