Detailed Description

Interface for acquiring video data using Intel's OPENCV library. Video data may either be provided from a file or a grabbing device. At the moment, OPENCV includes two separated modules for this grabbing, but only HighGui is used here. Initialize via SetVideoFileInput() or SetVideoCameraInput(), start processing with StartCapturing();
