An Image Compression Approach based on IWT and Grey Prediction

摘要：

A progressive image compression approach based on integer wavelet transform (IWT) and grey prediction is proposed. The compression approach is combining the EZW method and a grey prediction to compress images. IWT adopts lifting scheme and the grey prediction is based on the grey theory to further improve the compression rate withou degrading the image quality. Experiments show that the proposed approach has better performance.
