Abstract

A method for the rectification of figures and photos in printed documents using a single camera-captured image. The algorithm requires a bounding box for the objects in a single-view image. On receiving the bounding box, the desired image can be cropped for further processing. The main feature of segmentation method is that, it exploits the properties of printed figures to detect the boundaries using an optimization scheme. The boundary is extracted to obtain the boundary points and rectifying the distorted image is carried out using a dewarping method. The method improves the quality of output by largely removing perspective distortions. The rectified image having low resolution is converted to a higher resolution image using an edge directed interpolation method. Thus, an enhanced rectified output image is obtained as a result.
