Programmatically get non-overlapping images from MP4
16 novembre 2019, par Carlos FMy ultimate goal is to get meaningful snapshots from MP4 videos that are either 30 min or 1 hour long. "Meaningful" is a bit ambitious, so I have simplified my requirements.
The image should be crisp - non-overlapping, and ideally not blurry. Initially, I thought getting a keyframe would work, but I had no idea that keyframes could have overlapping images embedded in them like this :
Of course, some keyframe images look like this and those are much better :
I was wondering if someone might have source code to :
Take a sequence of say 10-15 continuous keyframes (jpg or png) and identify the best keyframe from all of them.
This must happen entirely programmatically. I found this paper : http://research.microsoft.com/pubs/68802/blur_determination_compressed.pdf
and felt that I could "rank" a few images based on the above paper, but then I was dissuaded by this link : Extracting DCT coefficients from encoded images and video given that my source video is an MP4. Of course, this confuses me because the input into the system is just a sequence of jpg images.
Another link that is interesting is :
Detection of Blur in Images/Video sequences
However, I am not sure if this will work for "overlapping" images.
