Enumeration Type Documentation

LPVEdgePreserveFilter

enum LPVEdgePreserveFilter

This enumeration represents the method for edge-preserving filter, useful for edge extraction, texture removal before segmentation. Since 2.17.0.

Enumerator
LPVEPFFastGuided	Fast guided filter, which speed up guided filter with almost no visible degradation. It may use a reference image to provide additional edge information. It may produce halo artifacts near strong textures. It is very fast, linear-time in image size, but may not smooth large low-contrast textures as aggressively as the other methods.
LPVEPFWeightedLS	Edge-preserving smoothing operator based on the weighted least squares optimization framework. It produces very smooth flat regions while preserving strong edges, works very well for base-detail decomposition. It usually has no halo artifacts. But it's much slower than the other methods and use more memory.
LPVEPFL0Smooth	Edge-preserving smoothing operator effectively forces most gradients to zero. It usually produces cartoon-like, piecewise-constant images. No halo artifacts are introduced. It's slower than LPVEPFFastGuided, faster than LPVEPFWeightedLS.
