Real time fractal image coder based on characteristic vector matching

چکیده
In this paper a new hardware method for fast and low power fractal coding is presented. The introduced method is based on binary classification of domain and range blocks. The technique not only reduces power consumption and increases processing speed but also has minimal effect on the degradation of the output result compared to the available fractal techniques. In order to show the functionality of the proposed algorithm, the architecture was implemented on a FPGA chip. It was further shown that the power consumption is reduced by the proposed architecture. The resulted compression ratios, PSNR error, gate count, compression speed and power consumption are compared against the existing designs. Applications of the proposed design in certain fields such as mass volume database coding are also discussed.

In this paper we are going to implement the hybrid wavelet coder to improve the gray image quality at low bit rate, such type of compression provide high compression ratio at low bit rate that means it overcome the drawback of fractal image coding in spatial domain produces the artefact blocking effect this effect can be reduces by using fractal image coder in wavelet domain and also this coder...
متن کاملFractal Coding by Means of Local Feature Histograms
This report describes an experimental still image coder that grew out of a project in the graduate course “Advanced Video Coding” in spring 2000. The project has investigated the idea to use local orientation histograms in fractal coding. Instead of performing a correlation-like grey-level matching of image regions, the block search is made by matching feature histograms of the block contents. ...
متن کاملImage coding based on a fractal theory of iterated contractive image transformations
The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations. The main characteristics of this approach are that (i) it relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis, and (ii) it approximates an original image by a fractal image. The author refers to ...
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 ...
