At decomposition level 3, coif3 provided
the cumulative error of value 2 compared to other
wavelets and it is shown in Table1. The
Table2 provides the CR and PSNR at level 3
compressed image. The compressed and classified
images using coif3 wavelet is shown in
Figure 4 and Figure 5 respectively. The error matrix
and the signature editor are shown in Table 3 and 4.
From the error matrix table it is found that 2 errors
are occurred out of 1358 samples. The Figure 6,
Figure 7 and Figure 8 shows the spectral signature
graph, compression ratio and peak signal to noise
ratio of the compressed image at level 3.
