Fast High-Dimensional Kernel Filtering using Nystrom Approximation

P. Nair, and K. N. Chaudhury, "Fast High-Dimensional Kernel Filtering,", in IEEE Signal Processing Letters

IMPORTANT POINTS

Main files in the code:

1. bilateral_approx.m - For bilateral filtering of high-dimensional images.
2. nlm_approx.m - For non-local means filtering of high-dimensional images.
3. 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
