Abstract

Abstract: Three channels of color image have a close correlation.Super resolution in the RGB space is easy to break the relevance and cause artifacts.However,there is a little relevance between three channels in the lαβ color space.In this paper,a new approach to achieve color image super resolution is presented,which used the concept of space conversion. Super resolution is performed separately in the lαβ channels.The experimental results demonstrate that the approach is effective and will minimally break the relevance between the color channels.

Key words: super resolution, RGB space, lαβ space
