Detailed Description#

the Median Flow tracker

Implementation of a paper MedianFlow .

The tracker is suitable for very smooth and predictable movements when object is visible throughout the whole sequence. It’s quite and accurate for this type of problems (in particular, it was shown by authors to outperform MIL). During the implementation period the code at http://www.aonsquared.co.uk/node/5, the courtesy of the author Arthur Amarra, was used for the reference purpose.
