Detailed Description

CDitherRemoval attempts to perform the reversal of image dithering, which is a common technique for printing with inkjet printers.

Dithering is analogous to the halftone technique used in printing. Due to the fact that during the dithering process a part of the image information is lost, the resulting image after the dithering removal will not be the same as the original. However, the resulting image would improve the recognition rate of iDRS recognition engines (both OCR and barcode).

Note: The algorithm works only for black & white images
