Abstract：In this paper, an integrated perspective distortion correction method is proposed aiming at the smallsquare document images acquired by the camera. The characteristics of smallsquare documents-small area, fewer words and complicated layout, boundaries of smallsquare document region extracted by color image segmentation methods as well as the text information in the document are used to correct the distortion. Experimental results show that this method can rectify the smallsquare document image effectively.
