Camera-captured document image perspective distortion correction using vanishing point detection based on Radon transform

Abstract

A correction method for perspective distortions on document images is discussed. In documents, lines and line feeds give rise to many horizontal and vertical lines, then two vanishing points generated by these lines can be computed. High-energy regions are identified in the Radon transform thanks to a binarization step. Then, the image is zero-padded and… (More)
