when I build your code, I get some error message:
singleeyefitter/build/spii/src/spii/examples/fields_of_experts.h:194:27: error: cannot convert ‘std::ifstream {aka std::basic_ifstream<char>}’ to ‘bool’ in initialization spii_assert(bool{foe_file});
note: in definition of macro ‘spii_assert’ #define spii_assert(expr, ...) (expr) ? ((void)0) : spii::verbose_error(#expr,

I'm trying to run the executable file SingleEyeFitterCmd but a little bit confused about the parameters we should feed.
std::cerr << "USAGE: " << argv[0] << " <folder> <filepattern> <fov> [<truthfile> [<init_num_added>]]" << std::endl;
Could you please explain the meaning of filepattern and what is the FOV for the dataset you used? Besides, are the last two parameters optional and their use case?
Thank you very much.

Hello,

I just tried installing singleeyefitter and I think there is a typo in your code. Right now you have on line 29 #include pupiltracker/pupiltracker.h

But it should be

include pupiltracker/PupilTracker.h

(the upper/lower casing causes "make" to crash) when I try to compile it.

Hi Leszek,
I'm very interested in this project. I already set up the environment for this, can you provide some sample input or explanation? I'm confused about what is expected as input here:
std::cerr << "USAGE: " << argv[0] << " <folder> <filepattern> <fov> [<truthfile> [<init_num_added>]]" << std::endl;

Another question, does the gaze_vector only comes from ground_truth? I saw the dataset you provide in link only has original eye images. Then how can we still get the gaze direction estimation?

Zhaoyan
