We present a modified structure of 2-D cdf 9/7 wavelet
transforms based on adaptive lifting in image coding. Instead
of alternately applying horizontal and vertical lifting, as in
present practice, Adaptive lifting performs lifting-based
prediction in local windows in the direction of high pixel
correlation. Hence, it adapts far better to the image orientation
features in local windows. The predicting and updating signals
of Adaptive lifting can be derived even at the fractional pixel
precision level to achieve high resolution, while still
maintaining perfect reconstruction. To enhance the
performance of adaptive based modified structure of 2-D CDF
9/7 is coupled with SPIHT coding algorithm to improve the
drawbacks of wavelet transform. Experimental results show
that the proposed modified scheme based image coding
technique outperforms JPEG 2000 in both PSNR and visual
quality, with the improvement up to 6.0 dB than existing
structure on images with rich orientation features .
