A core part of the ImageMorphology package is grayscale or binarized images. You have already learned how to create grayscale images. Binary images are those whose pixels are represented by either 1 or 0. Most of the examples you will find in this book and online have the following standard notation:
- 0 or black is used for the background
- 1 or white is used for the foreground, that is, our object
We will use the following code to create a binary image by a simple thresholding of a grayscale, that is, for example, assigning a 1 if the pixel value is over 0.5 and a 0 if it is below 0.5.
Binary and grayscale images are not perfect because they may contain numerous imperfections and are distorted by noise or texture. Morphological ...
