jit.uyvy2luma

Converts UYVY to monochrome (luminance)

Description

The jit.uyvy2luma object converts a 4-plane char UYVY (signed chroma blue, luminance left, signed chroma red, luminance right) matrix into a 1-plane char monochrome (luma) matrix. Horizontal dimension is doubled for the output to account for this half chroma, macro pixel input format. The UYVY format is typically useful for efficiently transfering chroma reduced codecs to the GPU without the expense of colorspace conversion, or bandwidth requirements of a full chroma format. However, to apply most spatial operations in Jitter on the CPU, a full chroma format like AYUV or ARGB is typically necessary.
