Graph cut opencv

WebThe Graph Cut technique applies graph theory to image processing to achieve fast segmentation. The technique creates a graph of the image where each pixel is a node connected by weighted edges. The higher the probability that pixels are related the higher the weight. The algorithm cuts along weak edges, achieving the segmentation of objects … WebApr 9, 2024 · Let’s code: hands-on OpenCV GrabCut Image Segmentation tutorial!
