Image binarization is the process of taking an image and convert it into black and white image. This process uses thresholds of RBG or Gray to assign black (0) or white (1) to a pixel. Binarization is usually use when trying to extract object from picture. ...
Converts an image to black-and-white image. Binary images are images whose pixels have only two possible intensity values. They are normally displayed as black and white. Numerically the two values are often 0 for black and 255 for white. Binary images a
