How to binarize an image

The simple binarization method with a fixed threshold BinarizeFixed is using only one parameter - a threshold with value from 0 to 255. All pixels in this case that have an intensity greater than the defined threshold will be set as a black color, or if less than the threshold, then to a white color. You can use a more precise binarize method `Bradly` BinarizeBradley to improve binarization quality. Method `Bradly` use the threshold as an average estimation intensity of the surrounding area with size `s x s`. In this case, the resulting picture will have smooth edges. Also, you can use `Otsu` method BinarizeOtsu with automatic threshold:
