Image binarization

This point operation produces binary images, i.e., images with sample values with two values only. The operation is sometimes described as thresholding.

y(n1,n2)	= 0 if u(n1,n2) < T
	= 1 otherwise,

where T is a predefined threshold.

Binarization may be viewed as very rough image quantization.

Binarization has wide applications as a preprocessing step in various image analysis operations.
