Conserved non-coding elements (CNEs) are defined using various degrees of sequence identity and thresholds of minimal length. Their conservation frequently exceeds the one observed for protein-coding sequences. We explored the chromosomal distribution of different classes of CNEs in the human genome. We employed two methodologies: the scaling of block entropy and box-counting, with the aim to a...

The main problem of fractal image compression is the long search time of the domain pool. For this reason, the dedicated ASIC architecture for fractal image coding is needed. In this paper, we propose an efcient parallel architecture for fractal image coding which is based on xed-size full-search algorithm. One of the main features of this architecture is that it uses only local communication s...

Abstract The image inpainting is an important problem image processing. It is a difficult problem to recover an image with bigger hole, and the existing algorithms are not give good method. Based on fractal theory, in this paper, we present a new inpainting method, which using the total info of image effectively. The relation of fractal dimension and the size range block is discussed, and give ...

| The well known drawback of fractal image coding is its heavy computation complexity. In this paper, we show however that only a very small portion of this complexity is needed to encode the contours and the smooth areas of the objects of a certain minimum size. This is simply achieved by a local search of the matching domain blocks without isometry. Therefore, instead of forcing the fractal c...

Most codon indices used today are based on highly biased nonrandom usage of codons in coding regions. The background of a coding or noncoding DNA sequence, however, is fairly random, and can be characterized as a random fractal. When a gene-finding algorithm incorporates multiple sources of information about coding regions, it becomes more successful. It is thus highly desirable to develop new ...

The Coordinate Logic (CL) Filters and their associated Coordinate Logic Operations (CLOs are used in image processing, pattern recognition and compression problems. The relationship between direct logic operations, fractal structures and algebraic structures are considered giving thus an insight to the issues related to image analysis and the interpretation of formal systems.CL filters provide ...

Since its introduction, fractal theory has been exploited in many research topics such as image processing, pattern recognition and image coding, because of the intrinsic properties which make fractals highly suited to tasks such as segmentation, feature extraction and indexing, just to name a few. Unfortunately, they are based on a strong asymmetric scheme, consequently suffering from very hig...

We undertake a study of the performance difference of different transform coding techniques i.e. block truncation coding (BTC), wavelet, embedded zerotree transform and fractal image compression. This paper focuses important features of transform coding in compression of still images, including the extent to which the quality of image is degraded by the process of compression and decompression....
