GrabCut Algorithm for Image Segmentation

How does GrabCut algorithm work?

GrabCut uses a user-defined bounding box to separate foreground and background, employing Gaussian Mixture Model and graph cuts for efficient image segmentation.

What is the difference between GrabCut and watershed?

GrabCut uses user input for segmentation, while watershed relies on image gradients. GrabCut is more interactive and suitable for object-specific segmentation.

Which mode of GrabCut initializes the state and the mask using the provided rectangle?

GC_INIT_WITH_RECT initializes the state and mask using the provided rectangle in GrabCut.

What is the difference between graph cut and GrabCut?

Graph cut is a broader term, while GrabCut is a specific algorithm utilizing graph cuts for image segmentation, particularly for foreground extraction.

What is a U net model? 

U-net is a convolutional neural network architecture used for image segmentation, particularly in medical image analysis, featuring a U-shaped structure for effective feature extraction and segmentation.
