I feel that it is similar to the research on “Advanced User Interfaces for Dynamic Video Browsing” by
. - In fact, it builds on top of the aforementioned research.
-
When you want to skim through a video, using the bar or an elastic video playback UI, it is difficult to understand the meaning of the video when fast-forwarding.
- This problem also occurs with an elastic video playback UI.
-
To solve this problem,
- First, extract keyframes (explained later).
- Then, select the obtained keyframes using a certain algorithm.
- Utilize the detected hierarchy.
- (You can understand more by reading the paper.)
-
How to extract keyframes (not the essence of the paper):
- First, select the middle of each range obtained from Shot Boundary Detection.
- Shot Boundary Detection is an algorithm that detects the places where the video switches.
- Extract short videos around each obtained place.
- Use color histograms to combine several videos into one.
- Repeat this process to create a hierarchy of videos.
- First, select the middle of each range obtained from Shot Boundary Detection.
