Applies the function (which should take one argument) to each pixel in the given image. If the image has more than one band, the same function is applied to each band.

WitrynaThresholding is one of the most basic techniques for what is called Image Segmentation. When you threshold an image, you get segments inside the image... each representing something. For example... complex segmentation algorithms might be able to segment out "house-like" structures in an image. With thresholding, you can …

Witryna16 sty 2024 · Thresholding-Based Image Segmentation. Image segmentation is the technique of subdividing an image into constituent sub-regions or distinct objects.
