4.3 Threshold segmentation
Threshold segmentation is the simplest method of segmenta-
tion of image objects as well as one of the most common
methods of parallel segmentation. It is a popular segmentation
algorithm that divides the information processing of the grayscale
image directly based on the gray value of various targets. Seg-
mentation of the threshold may be categorized into local
threshold method and global threshold method. An example of
region-based segmentation using deep learning approach is
shown in Fig. 10.7.
