Fail to compile in windows 7

[willard-yuan]

Hi Leszek,

I try to build the pupiltracker, and it throw the following error:

1>  utils.cpp
1>c:\program files (x86)\microsoft visual studio 10.0\vc\include\random(1604): error C2064: Entries are not calculated as a function of the parameter accepts 0

The environment is Windows 7 and VS 2010. I think the main reason lead to this is the int pupiltracker::random(int min, int max) and int pupiltracker::random(int min, int max, unsigned int seed). Would you tell me how to fix it?

VS2010 might be a bit old, can you try with 2015? You can download the community edition for free.

@LeszekSwirski I change it to OS X and it runs successfully. I have read your paper Robust real-time pupil tracking in highly off-axis images. I can fully understand the paper, but when I test it on a video or a picture, the result seems to be not good. The followings is a result I get:

then I change to a small eye image( I used a HOG with linear SVM to get the eye area), the result is as followings:

The fitted ellipse by RANSAC draw on the result image is smaller than the size of the gaze. I'm reading the code fully now. How do I tune the parameters to get a good result?

Have you adjusted the minimum and maximum pupil radius?

@LeszekSwirski I have adjusted the params.Radius_Min to 0 and params.Radius_Max to 50. Now it works great. Using the same image above, I get the result as follows:

I'm really interested in your research and found you have do a lot of work in gaze tracking and eye model fitting. I'm really appreciate for your help and your great works. Thanks!
