05.11.2018 · Instance Segmentation is a concept closely related to Object Detection. However, unlike Object Detection the output is a mask (or contour) containing the object instead of a bounding box. Unlike Semantic Segmentation, we do not label every pixel in the image; we are interested only in finding the boundaries of specific objects.

27.07.2020 · Previously, we learned how to initialize OpenCV’s GrabCut using bounding boxes — but there’s actually a second method to initialize GrabCut. Using masks, we can supply the approximate segmentation of the object in the image. GrabCut can then iteratively apply graph cuts to improve the segmentation and extract the foreground from the image.
