I think we are in agreement? What you are saying is that conversion from linear YUV to linear RGB is, indeed, linear.
Further, the transformation from Y'CrCb to gamma-encoded R'G'B' is also a linear operation. Right?
- jacobolus 5y agoIt depends what you want to do with the data. If you want to send your sRGB-profile Y'CbCr JPEG image directly to an sRGB display then you are done after applying a matrix. If you want to composite multiple images, do other intermediate processing, or display the image on an arbitrary non-sRGB display, you probably want to convert to a linear space along the way.
- david-gpu 5y agoSo we are in full agreement, then.
