Robust Optical Flow Computation Based on Least-Median-of-Squares Regression

  title={Robust Optical Flow Computation Based on Least-Median-of-Squares Regression},
  author={Ee Ping Ong and Michael Spann},
  journal={International Journal of Computer Vision},
An optical flow estimation technique is presented which is based on the least-median-of-squares (LMedS) robust regression algorithm enabling more accurate flow estimates to be computed in the vicinity of motion discontinuities. The flow is computed in a blockwise fashion using an affine model. Through the use of overlapping blocks coupled with a block shifting strategy, redundancy is introduced into the computation of the flow. This eliminates blocking effects common in most other techniques… CONTINUE READING
