Intensity Transformation

The functions described in this section perform different types of intensity transformation including reduction of the intensity levels in each channel of the image, intensity transformation using lookup tables, and mapping high dynamic range image (HDRI) into low dynamic range image (LDRI).

• ReduceBits
  Reduces the bit resolution of an image.
• LUT
  Maps an image by applying intensity transformation.
• LUT_Linear
  Maps an image by applying intensity transformation with linear interpolation.
• LUT_Cubic
  Maps an image by applying intensity transformation with cubic interpolation.
• LUTPalette, LUTPaletteSwap
  Maps an image by applying intensity transformation in accordance with a palette table.
• ToneMapLinear, ToneMapMean
  Maps an HDRI image to the LDRI image.
