library for computational photography

** port various filters from my library.**

• bilateral filter approxmations

  • separable
  • bilateral grid
  • constant time O(1) bilateral
  • real-time O(1) bilateral

• add dxt thresholding for denoising

• add super resolution demo for iterative back projection.

• add recursive birateral filter for gray, more efficient implimentaion, line by line chatching?

• add domain transform filter

  • add test for domain transform filter.6/11
  • add various simd implementation for RF filter.6/11
  • add SIMD V-direction ver.
  • add other implimentation of domain transform filter

• write detail enhancement document

• add detail enhancement class.

• add color joint nearest filter

• add test for stencil and parallel filtering.

• need stereo matching/cost filter for joint filtering.

• need sse implimmentation cvtColorBGRA2BGR,cvtColorBGR2BGRA

• need a floating birateral filter without LUT or quantization for back projection.
