The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity $${\displaystyle I_{i,j}}$$ is less than a fixed value called the threshold $${\displaystyle T}$$, or a white pixel if the pixel intensity is greater than that threshold. In the example image on the … Zobacz więcej In digital image processing, thresholding is the simplest method of segmenting images. From a grayscale image, thresholding can be used to create binary images. Zobacz więcej Multi-band images Color images can also be thresholded. One approach is to designate a separate threshold for each of the RGB components of the image … Zobacz więcej Thresholding will work best under certain conditions : • low level of noise • higher intra-class variance than … Zobacz więcej While in some cases, the threshold $${\displaystyle T}$$ can be selected manually by the user, there are many cases where the user wants the threshold to be automatically set by an algorithm.
