Share more footage / detections about opendatacam

[b-g]

@mmmmmmmmmmmmmmmm Please calculate as a first step all videos of MOOVELLAB/00_Projects/traffic-cam/08_data/footage tests/marienplatz-intersection-footage/videos with darknetVideo.js and various thresholds asap ... and share it afterwards with @tdurand by putting it in MOOVELLAB/00_Projects/traffic-cam/08_data/detection results (shared via GDrive with T.). Thanks!

Thanks @mmmmmmmmmmmmmmmm

@mmmmmmmmmmmmmmmm Sorry to bother you with that again, but when you have time could you send me a longer footage (saying 10 min) of the whole intersection with detections ? The footage you sent me was more of different perspective of it, but always 40s-1 min long. Many thanks !

PS: also the detections of the file you shared are not super good for the*.72.mp4 .

For example this file: detected_4_0.48.mp4 and this file detected_4_0.72.mp4 are the "same" and the detections are pretty bad with one, and with the other are good.

But I have even better detections for this clip here: https://github.com/moovel/lab-traffic-cam/blob/master/x-playground/no-decode-timecode/C0082-47mm-absolute.txt

Is there some rational explanation ?

@tdurand of course! I will send you a longer video this morning.

Regarding the quality of detection I tried different thresholds (0.24, 0.48. 0.72). Thats why some detection are pretty bad...

@mmmmmmmmmmmmmmmm also try lower ones (default is 0.24) and document it in the detection files ... If I remember correctly if doesn't make that much sense to go too much more conservative than the default thresholds. I would recommend to use the realtime darknet examples to get a feeling for the thresholds ... and then calculate the videos.
