Abstract
A system and method for detecting shot boundaries in video clips may generate a color frequency histogram for each tile of each frame of the video clip, according to a regular grid. The method may include comparing histograms of a given frame to corresponding histograms of an adjacent frame and computing a divergence descriptor for the given frame dependent on the average difference between the histograms. Various heuristics may be applied to the descriptor for each frame and the computed average descriptor of two or more leading or trailing frames to detect a shot boundary or another type of divergence between frames. A GUI may provide tools usable to identify clips on which to apply shot boundary detection and mechanisms to specify parameter values of the operation. The method may be implemented by program instructions stored on a computer readable medium and executable by one or more CPUs and/or GPUs.
