Sprite and Global Motion Compensation

Functions for sprite and Global Motion Compensation (GMC) are used in decoding processes of static sprites and in decoding/encoding processes of Video Object Layers with GMC.

• WarpInit_MPEG4
  Initializes IppiWarpSpec_MPEG4 structure for further usage in GMC or Sprite reconstruction.
• WarpGetSize_MPEG4
  Returns size of IppiWarpSpec_MPEG4 structure.
• WarpLuma_MPEG4
  Warps arbitrary rectangular luminance region.
• WarpChroma_MPEG4
  Warps arbitrary rectangular chrominance region.
• CalcGlobalMV_MPEG4
  Calculates Global Motion Vector for one macroblock.
• ChangeSpriteBrightness_MPEG4
  Change brightness after sprite warping.
