The least-squares approach implicitly assumes that the errors in the image data have a Gaussian distribution with zero mean. If one expects the window to contain a certain percentage of "outliers" (grossly wrong data values, that do not follow the "ordinary" Gaussian error distribution), one may use statistical analysis to detect them, and reduce their weight accordingly. The Lucas–Kanade method per se can be used only when the image flow vector between the tw… WebOptical Flow Monocular Visual-Inertial Odometry with Online Photometric Calibration - NASA/ADS.
