Till a few years back, a monochrome or
panchromatic (PAN) image is taken for
environmental monitoring and preparing the LULC
maps. Since some of the information is lost in these
images, there is a need for RGB colour images.
These colour images are compressed using various
compression techniques such as Discrete Fourier
Transform (DFT), Discrete Cosine Transform
(DCT) & Short Time Fourier Transform (STFT)
and the image quality is analysed using the
parameters like CR and PSNR[7]&[2]. The
drawbacks of the above techniques are blocking
artifact, blurring and ringing artifacts [10]. To
overcome these drawbacks, the wavelet transform is introduced. Previous works were carried out
using only one wavelet and its performance was
analysed. Sadashivappa and Anand (2008) have
analysed the performance (CR and PSNR) for a
large set of wavelets
