Active contours, or snakes, are computer-generated curves that move within images to find object boundaries (note that the 3D version is often known as deformable models or active surfaces in the literature). They are often used in computer vision and image analysis to detect and locate objects, and to describe their shape.

Image Segmentation. Image segmentation is the process of partitioning an image into parts or regions. This division into parts is often based on the characteristics of the pixels in the image. For example, one way to find regions in an image is to look for abrupt discontinuities in pixel values, which typically indicate edges.

A novel region-based active contour model (ACM) is proposed in this paper. It is implemented with a special processing named Selective Binary and Gaussian Filtering RegularizedLevel Set(SBGFRLS)method, which first selectively penalizes the level set function to be binary, and then uses a Gaussian smoothing kernel to regularize it.

Image segmentation is the process that enables this partitioning. In this method, each pixel is assigned a label, and pixels that share some characteristics are assigned the same label number. This technique is widely used in the medical domain to locate the object of interest. It is a technique to partition a digital image into multiple segments.

The active contour method has been one of the widely used techniques for image segmentation. The basic idea of active contour is to evolve a curve, subject to constraint from a given image, in order to detect objects in that image [9]. But sometimes images are very noisy. So it is very difficult to accurately define their boundaries. Segmentation of Medical images is.
