A64 Datasheet(Revision 1. YUV formats fall into two distinct groups, the packed formats where Y, U (Cb) and V (Cr) samples are packed together into macropixels which are stored in a single array, and the planar formats where each component is stored as a separate array, the final image being a fusing of the three separate planes. The key to writing fast computer vision code on Android is efficient conversion between image formats.
