+Implementation of a paper "Forward-Backward Error: Automatic Detection of Tracking Failures" by Z. Kalal, K. Mikolajczyk

+
+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.

+TrackerTLD
+----------------------
+
+TLD is a novel tracking framework that explicitly decomposes the long-term tracking task into tracking, learning
+ and detection. The tracker follows the object from frame to frame. The detector localizes all appearances that have been observed so
+ far and corrects the tracker if necessary. The learning estimates detector’s errors and updates it to avoid these errors in the future.
+The implementation is based on [TLD]_.
+
+The Median Flow algorithm (see above) was chosen as a tracking component in this implementation, following authors. Tracker is supposed to be able
+to handle rapid motions, partial occlusions, object absence etc.
