Fractal Image Compression Techniques
Image compression is an essential technology in multimedia and digital communication fields. Fractal image compression is a potential image compression scheme due to its potential high compression ratio, fast decompression and multi resolution properties. Fractal image compression utilizes the existence of self symmetry of images. Since Bransley gave the concept of fractal image compression in ...
متن کاملFractal based Image Compression techniques - A progress Report
One well-known loss-less image technique is DCT-based JPEG compression that is quite effective at low or moderate compression ratios, up to ratios of 20 or 25 to 1. Beyond this point, the image becomes very “blocky” as the compression increases and the image quality becomes too poor for practical use. Another drawback of JPEG compression is its resolution dependence. In order to “zoom-in” on a ...
متن کاملMultiresolution Modeling Using Fractal Image Compression Techniques
This work presents a new approach to the multiresolution modeling of polygonal meshes. This approach is based on the theoretically well-established fractal image compression techniques. A polygonal mesh is represented as a fractal using an iterated function system (IFS). In this way, a level of detail can be obtained over a region of the mesh by successively iterating the IFS. The main advantag...
متن کاملRegion-based fractal image compression
A fractal coder partitions an image into blocks that are coded via self-references to other parts of the image itself. We present a fractal coder that derives highly image-adaptive partitions and corresponding fractal codes in a time-efficient manner using a region-merging approach. The proposed merging strategy leads to improved rate-distortion performance compared to previously reported pure ...
متن کاملGenetic Algorithm based Fractal Image Compression
Fractal Image Compression is a lossy compression technique that has been developed in the early 1990s. Fractal image compression explores the self-similarity property of a natural image and utilizes the partitioned iterated function system (PIFS) to encode it. The fractal image compression problem had three major requirements: speeding up the compression algorithm, improving image quality and i...
