Computer Vision System Toolbox™ provides algorithms and tools for video processing. You can read and write from common video formats and apply common video processing algorithms such as deinterlacing and chroma resampling. You can also display results with text and graphics burned into the video. Adding graphics to video helps you visualize extracted information or debug a system design. You can insert graphics, such as markers, lines, and polygons to mark found features, delineate objects, or highlight other key features.
