Many distributed video coders are implemented using sophisticated error correction codes that use soft information ( conditional probabilities) as a priori knowledge. This a priori information models the dependency behavior between the input data and side-information. In this paper we analyze both a symbol and bit plane based approach using LDPC codes. We show that a bit planebased encoder has ...

In this paper we invoke a nonanticipative information Rate Distortion Function (RDF) for sources with memory, and we analyze its importance in probabilistic matching of the source to the channel so that transmission of a symbol-by-symbol code with memory without anticipation is optimal, with respect to an average distortion and excess distortion probability. We show achievability of the symbol-...

A new method for qualitative shape recognition and matching of objects in designs is presented in this paper. The approach consists of a reference-points information approach of the qualitative description of shapes considering qualitatively their angles, relative side length, concavities and convexities, and types of curvatures of the boundary. The shapes recognised are regular and non-regular...

The existing C++ compilers are designed to translate C++ source programs into target codes and then execute them. This translation method is that a compiler that translates C++ source programs to target codes has to be available for each platform. Reusability and portability of codes will also decrease because target codes have to be different for each platform they are run under. For that reas...

In his work on the information content of English text in 1951, Shannon described a method of recoding the input text, a technique which has apparently lain dormant for the ensuing 45 years. Whereas traditional compressors exploit symbol frequencies and symbol contexts, Shannon’s method adds the concept of “symbol ranking”, as in ‘the next symbol is the one 3rd most likely in the present contex...

Forest plots are frequently used to display the results of meta-analyses and have been published in the medical literature since 1988 (Lewis & Clarke, 2001). A review of forest plots reveals that the format chosen can affect the accuracy with which the information is conveyed to the reader. One formatting convention is the use of symbol areas to reflect the relative contributions, or weights, o...

We explore if there exist universal statistical patterns that are different in coding and noncoding DNA and can be found in all living organisms, regardless of their phylogenetic origin. We find that (i) the mutual information function [symbol: see text] has a significantly different functional form in coding and noncoding DNA. We further find that (ii) the probability distributions of the aver...
