ABSTRACT
The biggest group of processing operators exists for a class of images called the binary image. is is especially true for machine vision applications, where most of the color-and texture-related information is not of much use. In these applications, only certain areas of interest are isolated to be processed for further stages of processing. However, conversion to binary images is one of the essential preprocessing steps needed in machine vision processing. As discussed in Chapter 2, Section 2.5, a grayscale image can be converted to a binary image by thresholding the grayscale levels into two levels only: black and white. e next important information to be extracted from a grayscale image is related to the edges present in the image.
