Spatially Adaptive Block-Based Super-Resolution

Spatially Adaptive Block-Based Super-Resolution

ABSTRACT:

Super-resolution technology provides an effectiveway to increase image resolution by incorporating additionalinformation from successive input images or training samples.Various super-resolution algorithms have been proposed basedon different assumptions, and their relative performances candiffer in regions of different characteristics within a single image.Based on this observation, an adaptive algorithm is proposedin this paper to integrate a higher level image classificationtask and a lower level super-resolution process, in which weincorporate reconstruction-based super-resolution algorithms,single-image enhancement, and image/video classification intoa single comprehensive framework. The target high-resolutionimage plane is divided into adaptive-sized blocks, and differentsuitable super-resolution algorithms are automatically selected forthe blocks. Then, a deblocking process is applied to reduce blockedge artifacts. A new benchmark is also utilized to measure theperformance of super-resolution algorithms. Experimental resultswith real-life videos indicate encouraging improvements with ourmethod.
