Conclusions:
Development of filtering algorithms based on low-complexity SA-DCT:
- Denoising
- Deblurring
- Deblocking / Deringing
- Inverse-Halftoning (in preparation)
Algorithms are developed for grayscale and for color data
(with structural constraint for the chrominances)
State-of-the-art objective performance (PSNR) (outperforms best existing methods)
Proven superior subjective quality
Real-time applications can be considered by using MPEG4 hardware, which natively implements SA-DCT
