Abstract :
This work examines a 16-bit YCbCr (6:5:5) color representation for limited-memory, embedded video-processing applications. The 16-bit format, combined with YCbCr 4:2:0 video streams, reduces storage requirements by 29% over a 4:2:0 chroma format and 65% over a baseline 24-bit YCbCr format while providing satisfactory image quality and sufficient information for motion estimation.
