A fast method for scaling color images

Image scaling is an important processing step in any digital imaging chain containing a camera sensor and a display. Although resolutions of the mobile displays have increased to the level that is usable for imaging, images often have larger resolution than the mobile displays. In this paper we propose a software based fast and good quality image scaling procedure, which is suitable for mobile implementations. We describe our method in detail and we present experiments showing the performances of our approach on real images.
