Hey,
I have an interesting problem and I'm solving it with OpenCV. It's be
great if the solution could come straight from ffmpeg, though!
I need to:
1) cropdetect
2) crop surrounding borders from a video
3) resize video to normalize its dimensions
In other words, all I want is one command that will detect the frame-by-
frame borders and in the same step, crop it, and also resize it. And I
want this done for the entire video, not a single frame. It's gotta be
possible, right?
The applications are very useful in video analysis. I've spoken to
colleagues of mine and they are doing this manually themselves. It would
be great to be able to work this feature into the automation surrounding
ffmpeg in our tools. My personal application, for instance, is in
detecting videos that are similar using content perceptual hashing.
Another colleague of mine works for the Center for Missing and Exploited
Children. He does similar work, but with pHashing. I can see applications
for ContentID type systems across the board.
I'm sure this is a low on the totem pole request, but if you have any
spare cycles, this would really rock in the world of computer vision and
video analysis!
Thanks for your consideration,
--Collin
