NettetObserve how an intensity value 0 is mapped to obtain the corresponding value 0. In the limiting case shown in Fig. 2(b), 𝑇( ) produces a two level (binary) image. A mapping of this form is called a thresholding function. Some fairly simple yet powerful processing approaches can be formulated with intensity transformation functions. Nettet7. jun. 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.
