I have an image-based processing module that takes photos for some computer vision processing. I have many videos, but I need to sample representative frames as its inputs, preferably those frames with higher attention.
What are some good and effective algorithms or approaches to take K sample frames in a video? Interesting feature is that usually camera doesn't move much in successive frames with higher attention. So basically we have more stable scenes when a person is focusing on something important. Is there any ways to take this into account for our samlping?
