Keyframe extraction in surveillance video using correlation
B. F. Momin, Ganesh B. Rupnar · 2016
Video surveillance has been widely used in many applications. Public safety and theft protections are most important uses of it. A system like this needs an efficient transmission and storage of the large video data. Key frame extraction is a simple and powerful system to accomplish this objective. Keyframe extraction also called as a summary of the video because it gives the only important content of the video. Keyframing is used to summarize essential video content, hence it is very important for video data applications specially for surveillance where a lot of redundancy is present. Keyframes can be determined by considering motion as an important feature which can be calculated by using inter frame difference. Proposed method uses a correlation of colour channels to summarize video content.
