WebJun 1, 2024 · Global thresholding methods can be most efficient when the desired objects form prominent peaks in the gray-level histogram of the image. On the other hand, there are local thresholding techniques which are mostly used when an image has prominent local properties affecting the selected threshold. ... Dynamic thresholding of gray-level … WebJun 7, 2024 · Point Operation. Point operations are often used to change the grayscale range and distribution. The concept of point operation is to map every pixel onto a new image with a predefined transformation function. g (x, y) = T (f (x, y)) g (x, y) is the output image. T is an operator of intensity transformation. f (x, y) is the input image.
