WebJan 13, 2024 · Erosion — According to the OpenCV Documentation, the Erosion operator works similar to soil erosion. It “erodes”, or in simpler words, removes the boundaries of the foreground object in the image. The pixels at the boundary of the foreground object are removed. It reduces the size of the object in the image. Now we go for grabcut algorithm with OpenCV. OpenCV has the function, cv.grabCut()for this. We will see its arguments first: 1. img- Input image 2. mask - It is a mask image where we specify which areas are background, foreground or probable background/foreground etc. It is done by the following flags, … See more In this chapter 1. We will see GrabCut algorithm to extract foreground in images 2. We will create an interactive application for this.
