Virtual Magnifier-Based Image Resolution Enhancement

To obtain high resolution images, some low resolution images must be processed and enhanced. In the literature, the mapping from the low resolution image to the high resolution image is a linear system and it is only enlarged by an integer scale. This paper presents a real scaling algorithm for image resolution enhancement. Using a virtual magnifier, an image resolution can be enhanced by a real scale number. Experimental results demonstrate that the proposed algorithm has a high quality for the enlarged image in the human visual system.
