Runtime error in track() about libcmt HOT 5 OPEN

I got an error with your 2 images, but not at the same position than you (the error happened when all the detected features are in the selected area and no one outside), I committed an update on CMT.cpp and it works with your 2 images on my computer.
Can you try again and say me if it works?

Do you call cmt.initialise on the first frame before calling cmt.processFrame?

thanks

from libcmt.

It works on the two images and some other videos!
Yes, I did call cmt.initalise(im, topleft, bottomright) on the first frame.

In my codes, I just add the below since those two are not defined in C/C++. Do you think it makes any difference?
#define NAN (INT_MIN)
#define isnan(x) ( ((x)==NAN)? 1: 0 )

from libcmt.

INT_MIN may not be the best for define NAN but maybe it works.
The best solution is to compile with c++11 that defines NAN
I made a new commit with compatibility code that I have found on internet, it should work but maybe it's dependent of the compiler.

Thank you, delmottea, for your great work!
Quick questions:

• how can we check whether the tracker was intialized? is it (nbInitialKeypoints > 0)?
• should we nbInitialKeypoints = 0; in the CMT() constructor?
  Minor comment: since you are using OpenCV, can we just simply use CV_PI instead of M_PI?

from libcmt.

I've added nbInitialKeypoints = 0 in the constructor so you can use it to check if it's initialized.
and thanks for the CV_PI constant, I didn't thought to use it
