Survey of Different Key Frame Extraction Techniques

Now a day's social networking become a trend and through social networking we can share videos, audios, images and many more. But sometimes there is huge amount of unnecessary or redundant data is present in our videos so to reduce these types of data we use a method called key frame extraction method and to summarise that extracted data is done by a method known as video summarization .In last few years lot of work has been done on this area many new techniques and different algorithms are used. This paper does comparison of different key frame extraction techniques and also mentions their advantages and disadvantages and their limits.
