Our need is simple. We have an image with 8 colours, which includes white also as colour.
1. We print this image using laser printer or inkjet printer in a white paper. Paper quality may vary.
2. Scan/take a photo of the printed image. It will have white lines within a colours and it will occur because of printer quality.
3. After scan, we need to process the image and have to bring back to original image with right colors without white spots.
4. We use android and iphone's to take a picture of this image or flat bed scanner.
Create a DLL, where we can pass a scanned image as an input and it will return a clean image as an output..
