Image Quality Assessment for Different Wavelet Compression Techniques in a Visual Communication Framework

Table 1

IQA (MSE and MSSIM) metrics for different SNR and different wavelet compression methods.

SNR (dB)	Threshold compression; retained energy = 89.7377		Subband compression; retained energy = 89.7395
	Percentage MSE	MSSIM	Percentage MSE	MSSIM
5	30.415	0.0594	38.7395	0.0494
10	11.3305	0.1484	15.12	0.1234
15	2.4258	0.2966	2.8382	0.3010
25	1.6921	0.3188	1.6947	0.3304

Note that SNR (dB) = 10 * log₁₀ (signal · power/noise · power).
