This paper presents a new coding technique based on contourlet transform and multistage vector quantization. Wavelet based Algorithms for image compression results in high compression ratios compared to other compression techniques. Wavelets

Choice of Wavelets for Image Compression In wavelet-based image coding the choice of wavelets is crucial and determines the coding performance. Current techniques use computationally intensive search procedures to find the optimal basis (type,
