In difficult cases, thresholding will likely be imperfect and yield a binary image with false positives and false negatives. higher intra-class variance than inter-class variance, i.e., pixels from a same group have closer intensities to each other than to pixels of another group,.Thresholding will work best under certain conditions : Most of the binary automatic thresholding methods have a natural extension for multi-thresholding. The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity I i, j.
