Crashing after a face is detected with rcr_track.cpp #49

Closed ghost closed 6 years ago

ghost commented 7 years ago

I have tried to make the rcr-track.cpp code working, I copied the same file found inside: apps/rcr. the code detected a face with the landmarks in the first frame only and the program crashes!! I got the following:

capture

Any idea why that is happening?

Thank you!!

This looks a problem with either your video file or the decoder in OpenCV or ffmpeg (h264?). It doesn't look like it has anything to do with superviseddescent. I recommend you try different video files or formats or maybe a newer OpenCV version.

So now I tried different file formats. And I am using opencv3.2, and still it is not working. I got the following: capture I tried opencv alone with haar cascade face detection and it works in visual studio. So I guess it has nothing to do with opencv or ffmpeg.

I tried also the dlib library and it is working in visual studio on the same video files.

You don't get an error anymore so it looks like the video files in principle are running. I suggest you just debug through your app and see what happens - I'm sure it's probably some problem with the logic in your app. It doesn't look like any issue with superviseddescent.

Now it worked. The problem was with the following line: if (cv::waitKey(30) >= 0) break;

When I replaced it with: if (cv::waitKey(25) == 27) break; it works fine.

Note that I am using opencv 3.2

Finally, inside the else block at line 32, whenever I removed the comments I got the following errors: 1- I got an error on get_enclosing_box method since it takes a Mat and we are passing LandmarkCollection. How to solve this issue? 2- class "rcr::detection_model" has no member "model_mean" 3- name space rcr has no member "alignMean".

I'm going to close this, I don't think there is an issue in the superviseddescent library. Otherwise feel free to re-open.
