1. 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)
