Portable digital cameras have become omnipresent. Their low-lost, simplicity to use, flexibility, and good quality images have widened their applicability far beyond their original purpose of taking personal photos. Every day people discover new uses for them from photographing teaching boards to documents. One of the difficulties of using cameras is the occurrence of specular noise whenever the photographed object is glossy. This paper presents an efficient algorithm for removing the specular noise of photographed documents by taking multiple images with different illumination sources.
