Fast Edge-Preserving/Aware Filters for Image/Video Processing

•Gaussian filter as weighted average

•Bilateral filter (Note: anisotropic diffusion filter is equivalent)

–Separable bilateral filtering (range and spatial kernels);

•Fast bilateral filter

–Acceleration by piecewise linear approximation;

•Splatting (downsample), blurring (FFT) and slicing (upsample);

–Bilateral grid (importance sampling);

–Gaussian KD-tree;

–Pemutohedral Lattice.

•Fast Gauss (Transform) bilateral filtering;

–Constant time bilateral filtering O(1).

•Fast median (distributed histogram) filter

•Smooth local histogram filter and its acceleration

•Accelerated trilateral filter (gradient preserving)

•Domain Transform (DT) as a real-time edge preserving filter

•Patch Match

•Coherent Sensitivity Hashing (CSH)

•Propagation-assisted KD-tree
