Abstract
How to guarantee high image quality is the key point when converting standard-definition television (SDTV) images to high-definition television (HDTV) images. The change of pixel shape from rectangular to square makes traditional interpolation methods inappropriate because traditional methods are based on integer coordinates. In this paper, we propose a novel interpolation algorithm using center coordinates of pixels (IAUCCP). This method revises the color value of each pixel on HDTV images by correcting the pixels’ xy coordinates. After that, considering the huge enlarging multiples, sharpening treatment is done to the HDTV images. Experiments show that our method greatly improves the HDTV image quality comparing with traditional interpolation algorithms.
