Objective
- Create a program to implement high-dimensional filtering using the Adaptive Manifold algorithm.
Link to original paper
Edge-Aware Filtering
- Filter must take into account the values of the pixels, performing a 5D convolution (x, y, R, G, B)
- A lot of time wasted processing null areas
- Approximation using Adaptive Manifolds
- Build 1D manifolds approximating the original signal
- Project pixels on manifolds using gaussian weights
- Filter each 1D manifold individually
- Interpolate results based on Gauss-Hermite quadrature to approximate results
