Spatial Adaptive Prediction for Lifting Scheme in Image Compression

Wavelet transform has demonstrated excellent compression performance with natural images. However the performance suffers in the neighborhood of oriented edges. Under these conditions the Lifting style implementation of wavelets are widely used in image coders. The framework of lifting offers the flexibility for developing adaptive wavelet transforms. In this paper adaptive prediction techniques based on the local properties of the images are proposed. This adaptive lifting transform appears promising for image compression .
