Abstract

In this paper, we propose a method to enlarge and display images of picture with high precision and scalability taken by cellular phone on personal computer without producing jaggy noises. One of the major problems we face in image enlargement is the amplification of the jaggy edges. To deal with this problem, we first detect the edges, and approximate them using three kinds of functions including straight line, arc and quadratic curve. In addition, the color information of the enlarged image is determined by interpolation using quadratic Fluency DA function, which is subsequently merged with the edge information obtained earlier. This enables the construction of a high precision and scalable image that cannot be produced by conventional image coding method such as JPEG or MPEG.
