ABSTRACT

Image segmentation is a technique used to extract the foreground object from background image. In this paper Grabcut framework is used to extract the object from the background. Color and Texture feature is used as discriminating feature for object extraction. Region based image segmentation is done in this paper. For Texture feature extraction, Structure Tensor is used for finding the correct boundary/edge of the needed object. Smoothing is done using Anisotropic diffusion which will preserve the edges from dislocation. If dislocation in edges arises, it is difficult to get proper segmentation. In this paper, details of anisotropic diffusion is given and it tells how the image quality will be increased using this method.
