INTENSITY REDUCTION METHOD USING WAVELET FOR COMPRESSING GREY SCALE IMAGES
S. Vimala, D. Yesu Rani, M. Sangeetha
Abstract :
Image compression techniques are used to reduce the cost associated with storage and transmission.
They are classified into two types: (i) Lossy compression (ii) Lossless compression. In this paper, we have
proposed a novel approach, Intensity Reduction Method (IRM) to compress the images using Haar Wavelet. The feature of inter–pixel redundancy is exploited to achieve good compression ratio in this approach. Standard images like
Lena, Jet, Peppers, Barbara and Boats of size 256 x 256 pixels are tested with the proposed method which yields a
better PSNR (quality of the reconstructed image) than a few existing compression techniques. The computational complexity of the proposed method is also less when compared to that of existing techniques.
