  • 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.
