• Optical Flow Methods
  
  • calcOpticalFlowPyrLK - The iterative Lucas-Kanade method with pyramids (non-dense OFF)
  • calcOpticalFlowFarneback - Gunnar Farneback's algorithm (dense OFF)
  • the variational Oprical Flow method (dense OFF)
  • Stereo (1D OFF):
    
    • FindStereoCorrespondenceBM - computes the disparity map using block matching algorithm
    • FindStereoCorrespondenceCG - computes the disparity map using grapg cut-based algorithm
    • the variational disparity estimation
