WitrynaWorking of normalize () function in OpenCV. 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. The contrast of the image can be increased which helps in extracting the features from the image and in image segmentation … Witryna18 sty 2012 · Perhaps because you didn't pass any filename into imread(). Perhaps because you left off the [] in imshow(y, []). It's floating so unless it's in the range 0-1 you need to give [] as the second arg to imshow().
