CCSDS 122.0-B-1 (Grayscale) 44.06 dB 5.00 : 1 (240KB)
JPEG 2000 (Grayscale) 48.42 dB 5.00 : 1 (240KB)

Note 1: CCSDS 122.0-B-1 is a single component image compression standard. For YUV images, each component was compressed separatelly.
Note 2: H.264 grayscale support is implemented by using only the Luma component and providing the middle scale value to Chroma components.
