Clust Measures for Track-based Multi-camera Tracking

Implementation of "Track-clustering Error Evaluation for Track-based Multi-Camera Tracking System Employing Human Re-identification". CW. Wu, MT. Zhong, SY. Chien, YK. Chen, SW. Yang, Y. Tsao. CVPR 2017 workshop on re-identification and multi-target multi-camera tracking.[1]

Note that this is developed based on DukeMTMC's evaluation kit v1.00, included in the MOT challenge. For more detail regarding DukeMTMC's multi-camera tracking dataset[2], please refer to their website:

• MOT challenge: http://motchallenge.net

• DukeMTMC: http://vision.cs.duke.edu/DukeMTMC

Graet thanks to Ergys Ristani for letting us to use his code!

If you have any problems or come across any bugs, please contact [email protected].

Requirement

• MATLAB (tested on Windows only with MATLAB R2016b & 2013a)

Usage

Run demoDukeMTMCEvaluate.m and it will compute T-MCT and MCT score for DukeMTMC's baseline results on the "val" set.

This is what you should expect for after ~30 min.:

For computing CLEAR measures for SCT at the same time, please execute the script demoDukeMTMCEvaluate_with_SCT.m. Expect about 1~2 hr. for the results if tested on "val" set (~25 min. long).

More detail can be found in our paper.

Some Notes

• 3D world plane evaluation is not supported.
• Calucating CLEAR measures take a lot of time, so we single out the script with it incorperated in.
• Results of our ReID-MCT system will be added later.
