Enhanced fractal image coding by combining IFS and VQ
Since the landmark paper in 1992 by A. Jacquin [1] on image coding with iterated function systems (IFS), many authors have studied IFS (or "fractal") and proposed many improvements to Jacquin’s algorithm [2]. While IFS has been viewed as a promising technique that might overtake more established coding methods, generally it has not so far lived up to these expectations. One fundamental problem ...
متن کاملGenetic Algorithms for Fractal Image and Image Sequence Compression
In this paper we present a method that uses Genetic Algorithms (GAs) to find a Local Iterated Function System (LIFS) that encodes a single image. By doing this, the time needed to achieve this LIFS is reduced by about 30% compared with Barnsley’s method if similar image quality is desired. If less quality is acceptable, using a GA we can vary the time the encoding will take by changing paramete...
متن کاملAn Improved Fast Fractal Image Compression Coding Method
The main purpose of image compression is to use as many bits as possible to represent the source image by eliminating the image redundancy with acceptable restoration. Fractal image compression coding has achieved good results in the field of image compression due to its high compression ratio, fast decoding speed as well as independency between decoding image and resolution. However, there is ...
متن کاملParallel Algorithms for Fractal Image Coding on Mimd Architectures
In this paper parallel algorithms for fractal image coding on MIMD architectures are introduced and discussed. It turns out that the crucial point for the choice of a suitable parallelization strategy is the memory capacity of a processor element. Experimental results show a linear speedup of the proposed algorithms.
متن کاملIFS Fractal Code for Image Retrieval on Compression Domain
Digital image databases represent huge amount of data, automatic indexing and content base retrieval are crucial factors. IFS ( Iterated function system ) fractal code can be used to retrieve image and the position parameter of IFS code is replaced with the relative distance and direction parameter. A new algorithm of IFS fractal code for image retrieval on compression domain is presented in th...
