The compromise for achieving this efficiency is the dependency of the programs length on the length of the transform, i.e., for longer transforms longer programs are generated. But the complexity order of the program length is N loglog N, and the proportionality constant is small, resulting in the program lengths shown in Table IV. These results are of real practical significance and can be imm...

This paper describes the fast computation, and some applications, of entropies and mutual information for color and multispectral images. It is based on the compact coding and fast processing of multidimensional histograms for digital images.

The trend in programmable architectures for digital signal processing (DSP) is to move towards high-level language programming, which sets high requirements for compilers to efficiently exploit the instruction level parallelism in modern processors. In this paper, efficiency of transport triggered architectures (TTA) in DSP applications is discussed. The efficiency of a high-level compiler on a...

Quantum-dot cellular automaton (QCA) is a novel nanotechnology with a very different computational method in compared with CMOS, whereas placement of electrons in cells indicates digital information. This nanotechnology with specifications such as fast speed, high parallel processing, small area, low power consumption and higher switching frequency becomes a promising candidate for CMOS tec...

introduction many features, emerging from mathematical techniques, have been used in the analysis of brain signals. in this study, the physical quantity of “moment of inertia” (moi) was introduced as a feature to enhance high-frequency waves (hfws) in electroencephalography (eeg). materials and methods in this research, the recorded eegs from f3, f4, and cz points in 20 males were used. a total...

introduction: tracking temporal changes of temperature during laser skin treatment plays an important role in improving the process of laser skin treatment itself. there are a number of methods to analyze temperature’s temporal dependency during laser skin treatment; some of those methods depend on imaging the skin with thermal cameras. however, the use of thermal cameras exhibits specific prob...

Previous studies have demonstrated that successful listening with advanced signal processing in digital hearing aids is associated with individual cognitive capacity, particularly working memory capacity (WMC). This study aimed to examine the relationship between cognitive abilities (cognitive processing speed and WMC) and individual listeners' responses to digital signal processing settings in...

This application note describes the basics of the Fast Fourier Transform and how to use a Digital Signal Processing Library. The library and design example use Microchip’s dsPIC30F Series Digital Signal Controller, specifically the dsPIC30F3013. The Transform Analysis discusses the differences between the Discrete Fourier Transform (DFT) and the Fast Fourier Transform (FFT), and how the FFT is ...
