Demo . Now we go for grabcut algorithm with OpenCV. OpenCV has the function, cv.grabCut() for this. We will see its arguments first: img - Input image; mask - It is a mask image where we specify which areas are background, foreground or probable background/foreground etc.

03.12.2020 · OpenCV. OpenCV provides a built-in function cv2.grabCut () that implements the GrabCut algorithm. This provides both the modes, with a rectangle or with a mask as discussed above. The syntax is given below. mask, bgdModel, fgdModel = cv2.grabCut (img, mask, rect, bgdModel, fgdModel, iterCount [, mode]) 1. 2.

28.09.2020 · In this tutorial, you will learn how to perform image segmentation with Mask R-CNN, GrabCut, and OpenCV. A couple months ago, you learned how to use the GrabCut algorithm to segment foreground objects from the background. GrabCut worked fairly well but required that we manually supply where in the input image the object was so that GrabCut could apply its …

Grabcut output is the mask, not a complete segmented multichannel image.. What you need to do is convert the output mask into the alpha channel of your image; for this, best use "Split" on the input RGBA to separate the channels, discard the input A channel, and "Merge" back into the output RGBA the RGB channels from the input with the mask from Grabcut.
