In this paper, we report application procedures and observed results of multi-resolution Fourier analysis proposed in the first part of this series. Missing signal recovery derived from multi-resolution theory is developed. It is shown that multi-resolution Fourier analysis enhances dramatically performances of Fourier spectra suffering limitations traced to implicit time windowing. Observed fr...
objective: iqspect is an advanced high-speed spect modality for performing myocardial perfusion imaging (mpi), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. the aim of this study was to compare iqspect compared with conventional spect interms of performance based on standard clinical protocols. in addition, we examined the concordance between conventional...
Multi-electrode arrays technology for the non-invasive recording of neural signals: a review article
The recording of electrophysiological activities of brain neurons in the last half-century has been considered as one of the effective tools for the development of neuroscience. One of the techniques for recording the activity of nerve cells is the multi-electrode arrays (MEAs). Microelectrode arrays (MEAs) are usually employed to record electrical signals from electrogenic cells like neurons o...
License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...
Analyzing network traffic activities is imperative in security to detect attack patterns. Due the complex nature of event caused by continuously changing computing environments and software applications, identifying patterns one challenging research topics. This study focuses on analyzing effectiveness integrating Multi-Resolution Analysis (MRA) visualization activities. In detail, a Discrete W...
We propose a three dimensional multi-resolution scheme to represent volumetric data in resolutions which are powers of two, resolving the rigidity of the commonly used separable Cartesian multi-resolution schemes in 3D that only allow for change of resolution by a power of eight. Through in-depth comparisons with the counterpart resampling solutions on the Cartesian lattice, we demonstrate the ...
