Color Space Formatting and Conversions

Perform video format and data type conversion

You can apply common video processing algorithms to images or video, such as deinterlacing, chroma-resampling, and color space formatting and conversions. You can also use color space functionality from the Image Processing Toolbox™.

System Objects

vision.ChromaResampler Downsample or upsample chrominance components of images
vision.DemosaicInterpolator Bayer-pattern image conversion to true color
vision.GammaCorrector Apply or remove gamma correction from images or video streams

Video and Image Formats

Video Formats

Video data is a series of images over time.

Image Formats

In the Computer Vision System Toolbox™ software, images are real-valued ordered sets of color or intensity data.
