NirT 0:c00e6c923941 34
NirT 0:c00e6c923941 35 Component - Color channel, e.g., Red or Luminance.
NirT 0:c00e6c923941 36 Sample - Single component value (i.e., one number in the image data).
NirT 0:c00e6c923941 37 Coefficient - Frequency coefficient (a DCT transform output number).
NirT 0:c00e6c923941 38 Block - 8x8 group of samples or coefficients.
NirT 0:c00e6c923941 39 MCU - (Minimum Coded Unit) is an interleaved set of blocks of size
NirT 0:c00e6c923941 40 determined by the sampling factors, or a single block in a
NirT 0:c00e6c923941 41 noninterleaved scan.
