Image binarization is a process that converts a greyscale or colour image into a black & white image.
One of the reasons to convert images is to save considerable space required to store documents on a disk. On the other hand, it is a lossy conversion and ordinary methods which use a single threshold can result in poor image quality and loss of important data.
Our binarization procedures compute a different threshold for each pixel in the image, preserving information which would be lost lost during fixed threshold conversion.
