Hi
I try to running MOT_cross_validation.m after run compile.m and fix problem of dataset path.
After running MOT_cross_validation.m I get below log and errors:

MOT_cross_validation
Warning: Name is nonexistent or not a directory:

initialize tracker from scratch
Error using svmtrain (line 234)
Y must be a vector or a character array.

Error in MDP_initialize (line 28)
tracker.w_active = svmtrain(tracker.lactive, tracker.factive, '-c 1 -q');

Error in MDP_train (line 49)
tracker = MDP_initialize(I, dres_det, labels, opt);

Error in MOT_cross_validation (line 39)
tracker = MDP_train(idx_train{j}, tracker);

And my system have below specifics:
Windows 10 x64
Matlab 2015b
OpenCv 2.49
Visual studio 2012

so, How can fix this error and run this code completely successfully?

you are using the svm toolbox of matlab instead of libsvm because the prepared libsvm in the code is not compiled with windows and visual studio. you just need to compile libsvm again:

  1. change current path to 3rd_party/libsvm-3.20/matlab
  2. in matlab command run "mex -setup C++"
  3. then run "make" and you get four *.mexw64 files, done
