Reconstruction+Synthesis:A Hybrid Method for Multi-Frame Super-Resolution

In this paper a new method for multi-frame Super-Resolution is proposed. Having a low resolution(LR) video and a few high resolution(HR) images from a speci¯c scene is frequently occurred. In addition it is usual that between images and video frames there is some di®erences, because of di®erent of exposure time, moving objects, camera movement and so on. In the proposed method a Super-Resolution reconstruction method, applies on low-resolution frames for producing a reconstructed HR image. After that a synthesized image with mapping the high resolution training image to the reconstruction result, is produced using a proper transformation model. Fusion of the synthesized image with the reconstruction result makes the ¯nal desired HR image of the given LR frames. Experimental results show that our approach is competitive both for quality and quantity with some famous super-resolution methods.
