The gap between KCFcpp and KCFpy? #2

Open GarrickLin opened 7 years ago

GarrickLin commented 7 years ago

I have run your code, but I found the performance has some gap between these cpp and py version. 

1. the cpp version has a better scale invariance
2. the py version is easily tend to lose target

and I still run some other version of cpp code such as vojirt/kcf and foolwood/KCF, they remain the same problems.

Do you have worked out this weird problem?

Sorry for my late reply. Did you change the parameters in line 59 in 'run.py', if you didn't, it may explain your question: tracker = kcftracker.KCFTracker(False, True, False) # hog, fixed_window, multiscale

You can set the first parameter True for tracking robustness, and set the third parameter True for scale invariance. (I update it now) I haven't test the the code systematically, so although this code is translated line-by-line from KCFcpp, there may still be some problems.

Thank you very much!
