Paper Abstract

Although the resolution of digital imaging device is rapidly increasing these days, digital photography still suffers from resolution limits when we want to enlarge a small picture. It is widely believed that edges play the important role when we evaluate the perceptual quality of resized images, and several edge-directed approaches have been proposed to soothe unwanted edge effects: jagging and blurring Edge-only-directed interpolations generally produce crispier edges than traditional interpolations such as bi-linear or bi-cubic, but they usually take longer time and sometimes create unacceptable defects where their edge estimation is incorrect. In this paper, we will address a new approach to compensate for blurring and aliasing effects using edge and corner cues in a given image.
