Outline of Final Research Achievements

We have developed a super-resolution system that consits of TV(Total Variation) reguralization filter and Shock filter. The input image is devided into the structure component and the texture component. The structure component is enhanced by the shock filter, and the texture component is enhanced by the pulse enhancement filter. The result is much better than the conventuional method. This system is implemented on the GPU. The conputational time is less than 16.7msec that is 1 frame time of the television. This enable that the system can be implemented on 4K-HDTV. Its also applicable to the medical image.In the future, since FPGA implementation will be required, we study FPGA implementation of this system.
