WebJan 8, 2013 · Then a mincut algorithm is used to segment the graph. It cuts the graph into two separating source node and sink node with minimum cost function. The cost function is the sum of all weights of the edges that are cut. After the cut, all the pixels connected to Source node become foreground and those connected to Sink node become background. WebWorking of normalize () function in OpenCV is as follows: The process in which we modify the intensity values of pixels in a given image to make the image more appealing to the senses is called normalization of the image.
