Visualizing optical flow files. #71

Closed letatanu closed 7 years ago

letatanu commented 7 years ago

Hi, I generate successfully the optical flow files from my video by Flownet2. However, when I use code gave by http://vision.middlebury.edu to visualize optical flow file, the code cannot read optical flow file. I also use another code to read the optical flow files, still get error in reading files. I wonder if the optical flow files generated from Flownet2 have the same structure as other optical flow files. Thank you.

Hey,

Could you please tell me how did you calculate it for a video file. I am stuck to use it for a mp4/avi file

@letatanu The FlowNet2 generates FLO files. The code you link to should be able to read it. What error are you getting?

@Maryada-27 We do not support video files directly, but you can convert the video into individual frames (e.g. using ffmpeg: ffmpeg -i your_video.avi -f image2 frame_%05d.png). Then you can feed those frames into the FlowNet via the "run_flownet_many" script.

@letatanu @Maryada-27 Is this issue still relevant, or can it be closed?

Maryada-27 commented 7 years ago

Yes please... Thanks a lot

@nikolausmayer It's my code error. Now I'm able to read FLO files. Thank you so much.
