Efficient Super Resolution Using Edge Directed Unsharp Masking Sharpening Method

This paper investigated the potential of the real-time implementation in single image super resolution using edge directed unsharp masking sharpening (EDUMS) method. To achieve efficient real-time implementation with unsharp masking sharpening, the resolution enhancement process needed only simply filtering operations without iterations. Also, with edge directed information as the prior of the unsharp masking sharpening method, the jaggy artifact was efficiently suppressed. Clear edge structures and vivid details of high resolution images with minimum artifacts were presented by the proposed method.
