P. Nair, and K. N. Chaudhury, "Fast High-Dimensional Kernel Filtering,", in IEEE Signal Processing Letters
IMPORTANT POINTS
Main files in the code:
- bilateral_approx.m - For bilateral filtering of high-dimensional images.
- nlm_approx.m - For non-local means filtering of high-dimensional images.
- bilateralHSdenoise.m - For hyperspectal filtering.
If you need to use O(1) Gaussian filtering, you have to create mex file for young.cpp using the command mex young.cpp
