GPU Accelerated Image Super-Resolution What? GPU based, real-time, single-image approach for super-resolution Why? Super-resolution is needed everywhere! (games, applications, mobile…) Existing algorithms are too slow for real-time processing Existing algorithms also have problems: Original Fattal et al.: Mosaic Pattern Glasner et al.: extra features How? Two-pass algorithm: Pass 1: Obtain gradient and high-pass textures Pass 2: High-pass along contour line (Step2) Adjust contours via erosion and dilation (Step3) - Low-pass along gradient direction of high-passed texture (Step4) Fei Yue, Stanford University 1
