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.

Abstract: Methods and apparatus implementing a technique for printing to a selected destination in a computer system. A centralized print manager provides the implementation and control of operation for print services, such as tile printing or color separations. In general, in one aspect, the technique includes: generating print events to provide a specific print service to a client application, where the print events request information from the client application according to the specific print service; and receiving responses to the print events from the client application, where at least one response includes print data to be printed to a destination.
