2.2 Wavelets
The various wavelets used for the compression
are Haar, DaubechiesN (dbN), CoifletN (coifN),
SymletN (symN), BiorthogonalN (biorN), Reverse
biorthognalN (rbioN) and discrete Meyer wavelet
(dmey), where N represents the number of
coefficients which specify the number of vanishing
moments and zero moments[9].
This research work is carried out in two methods.
The first method is based on the minimum
cumulative error of the DN values and the second
one is evaluation by image classification and
ground truth.
