Detailed Documentation
In the field of image segmentation, three GraphCut-based methods are widely used: GrabCut, LazySnapping, and Improved GrabCut. These implementations utilize MATLAB and VC++ hybrid programming, where mex files must be compiled before calling the core segmentation algorithms. The GrabCut method employs iterative energy minimization using Gaussian Mixture Models (GMMs) for foreground/background modeling. LazySnapping provides interactive segmentation with quick response through precomputed superpixels and graph construction. The Improved GrabCut enhances traditional GrabCut by incorporating edge constraints and adaptive initialization. These methods significantly improve segmentation accuracy and computational efficiency, enabling better understanding and processing of image data through optimized graph cut operations and energy minimization techniques.
