5. Performance
The efficiency of a compression format depends on intrinsic and extrinsic factors.
5.1 Intrinsic factors
Intrinsic performance factors, i.e. those directly linked to codec specifications, depend on :
1) the type of algorithm used, for example in image compression: DCT (with JPEG, MPEG... formats) or DWT (with JPEG 2000 format) for still or moving images (figure 13 );
-
2) the compression format itself, for example :
MPEG Audio compared to G.722/G.723...
