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. WebThresholding. Thresholding is used to create a binary image from a grayscale image [ 1]. We illustrate how to apply one of these thresholding algorithms. Otsu’s method [ 2] calculates an “optimal” threshold (marked by a red line in the histogram below) by maximizing the variance between two classes of pixels, which are separated by the ...
