Paper Abstract

Video slide shows constitute a very frequent video type. Typically, in order to produce such a video, a series of still images are used and processed. We present a method to solve the video slide show inversion problem where we are given a video slide show and we wish to extract the sequence of still images that have been used to produce this video. Our approach relies on a fast and efficient key-frame extraction method that partitions the video into content homogeneous segments and extracts a representative key-frame for each video segment. An important characteristic of this method is that the number of key-frames is determined automatically. Next, the set of key-frames is further processed to solve various problems such as mixing of images, fade-in/fade-out and zooming effects that produce keyframes not belonging to the original image sequence, thus they must be detected and discarded. We provide illustrative examples from the application of the method on several video slide shows with different characteristics.
