Abstract
A content-adaptive video preview system () allows to go faster through a video than existing video skimming techniques. Thereby, a user can interactively adapt (S) the speed of browsing and/or the abstraction level of presentation. According to one embodiment of the invention, this adaptation procedure (S) is realized by the following steps: First, differences between precalculated spatial color histograms associated with chronologically subsequent pairs of video frames said video file is composed of are calculated (S). Then, these differences and/or a cumulative difference value representing the sum of these differences are compared (S) to a predefined redundancy threshold (S(t)). In case differences in the color histograms of particular video frames (-) and/or said cumulative difference value exceed this redundancy threshold (S(t)), these video frames are selected (S) for the preview. Intermediate video frames (-) are removed and/or inserted (S) between each pair of selected chronologically subsequent video frames depending on the selected abstraction level of presentation. Thereby, said redundancy threshold value (S(t)) can be adapted (S') for changing the speed of browsing and/or the abstraction level of presentation.
