An efficient recursive edge-aware filter

作者：

Highlights：

• A novel edge-aware filtering with constant time complexity.

• Recursive weighted summation yielding window size independency.

• Soft weighting via effective connected support regions

• Low number of operations per pixel per disparity (6 adds and 4 muls) during aggregation.

• Multi-directional support.
