Hybrid Image Compression Using Fractal-Wavelet Prediction
Based on the standard fractal transformation in the spatial domain, simple relations may be found relating coefficients in detail(high-pass) subbands in the wavelet domain. In this paper, we devise a hybrid image compression using fractal-wavelet prediction where the causal similarity among blocks of different subbands in a wavelet decomposition of the image is exploited. The proposed coding sc...
متن کاملEnhanced Fractal Image Compression using Haar Wavelet
Fractal image compression offers a high compression ratio with extremely short decompression time. However, it suffered from long compression time. In this paper, a new block classification method based on the Haar wavelet transform is introduced. When used in conjunction with our domain block pool reduction scheme, the enhanced method can improve the speed of compression over 50 times with min...
متن کاملWavelet and Fractal Transforms for Image Compression
The main idea behind all fractal coding algorithms is to exploit the similarities present within many natural images: one block of an image is represented by an affine transform of another larger block taken from the image itself [1, 2, 3]. The characteristic property of fractal coders is to exploit similarities between different scales. Wavelet transforms perform multiresolution decompositions...
متن کاملImage compression with a hybrid wavelet-fractal coder
A hybrid wavelet-fractal coder (WFC) for image compression is proposed. The WFC uses the fractal contractive mapping to predict the wavelet coefficients of the higher resolution from those of the lower resolution and then encode the prediction residue with a bitplane wavelet coder. The fractal prediction is adaptively applied only to regions where the rate saving offered by fractal prediction j...
متن کاملA wavelet-based analysis of fractal image compression
Why does fractal image compression work? What is the implicit image model underlying fractal block coding? How can we characterize the types of images for which fractal block coders will work well? These are the central issues we address. We introduce a new wavelet-based framework for analyzing block-based fractal compression schemes. Within this framework we are able to draw upon insights from...
