How to use matlab grabcut

Grabcut is an improved image segmentation algorithm based on graph cut and graph cut theory. For a brief introduction of graph cut, please refer to my previous blog post: A preliminary understanding of some knowledge points _8 (graph cut, ing ...). After reading some papers on grabcut, I generally improve graph cut, such as introducing GMM model. Just like graph cutting, human-computer interaction is needed when using grabcut, that is, the target or background of a certain area is given manually, and then it is sent to grabcut algorithm for segmentation. Experiments show that the segmentation effect is average and the segmentation speed is slow, and a picture of ordinary size needs about1s.
