Correcting Photometric Distortion of Document Images on a Smartphone
AbstractThis paper presents efficient and robust methods for correcting photometric distortion on document images caused by moire pattern noise and specular highlight in smartphone. Our algorithm uses separated smoothing process for moire pattern removal on recaptured document image from LCD monitor. Furthermore, contrast of characters in specular highlight area is enhanced using subtraction and noise removal technique.
