YUV Color Space

YUV is a color representation that separates brightness, called luminance or Y, from color information carried in the U and V chrominance channels. Video systems can preserve more brightness detail while compressing color more heavily because human vision is generally more sensitive to luminance changes. Computer vision pipelines encounter YUV in cameras, codecs, streaming, surveillance, mobile devices, and real-time inference. Models may expect RGB input, so conversion, channel range, subsampling, and color standards must be handled consistently. Incorrect assumptions can shift colors or reduce accuracy without causing an obvious software error. Testing should use frames captured through the actual production pipeline rather than only clean converted images.
