WebThresholding Thresholding is a simple image preprocessing or filtering method that replaces: each pixel value in the image matrix with: 0 (representing dark) if the existing pixel is less than the constant value K 255 (representing bright) if the existing pixel value is more than the constant value K WebChapter outline. Morphological operations can be used to refine or modify the shapes of objects in images. Many morphological operations can be applied to binary images to improve an image segmentation. Grayscale morphological operations can also be used as processing steps before binarization, or to help identify regional maxima and minima.
