Video Formats and Interfaces
Convert between frame-based video and pixel streams
Hardware video processing algorithms operate on serial data. For information on the serial protocol used in Vision HDL Toolbox™, seeStreaming Pixel Interface.
You can simulate hardware-friendly streaming-pixel designs alongside frame-based designs. For instance, use frame-based algorithms, such as those designed using Computer Vision Toolbox™ or Image Processing Toolbox™, to verify a hardware-optimized design. Use the帧To PixelsandPixels To Frameblocks to convert video between frame-based and streaming-pixel formats.
