Abstract

This paper presents efficient and robust methods for correcting photometric distortion on document images caused by moir'e pattern noise and specular highlight in smartphone. Our algorithm uses separated smoothing process for moir'e 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.
