I. Comparison on lossy compression

Here reported are testing results using the standard Kodak image Birds (768x512x24). For JPEG2000 and JPEG, we used LuraWave SmartCompress. Data in the test settings are: quantization parameter for Lucid, file size (KB) for JPEG2000, quality factor for JPEG and Google WebP, quantization factor for JPEG XR. (*) WebP reaches 250:1 when quality factor = 1.

ratio ( :1)	20	32	48	56	64	100	150	200	300
Lucid	0.5	0.75	1	1.25	1.5	2	3	3.75	5.25
JPEG	86	71	43	33	26	11	1
JPEG2000	60.7	36	24	20	18	11.5	7.6	5.84	3.96
JPEG XR	25	37	47	50	54	65	73	80	88
WebP	92	86	78	74	63	33	13	5	1(*)
