INTERACTIVE LIVER TUMOR SEGMENTATION USING GRAPHCUT AND GRABCUT

Vishnu Priya D, Uma Maheswari R

Abstract: This literature review attempts to provide a brief overview of the most common segmentation techniques, and a comparison between them. It discusses the “Grab-Cut” technique, and" Graph Cut" techniques. GrabCut is a way to perform 2D segmentation in an image that is very user friendly. The user only need to input a very rough segmentation between foreground and background .The Graph Cut approaches to segmentation can be extended to 3-D data and can be used for segmenting 3-D volumes. Other segmentation techniques use either contour or edge segmentation to perform segmentation. The Graph Cut techniques use both contour and edge detection. Typically this is down by drawing a rectangle around the object of interest. The way that this is accomplished technically is by using a combination of Graph Cuts and statistical models of the foreground and background structure in the colour space. Grab Cut Technique use very minimum energy to separate Foreground and Background Images.
