PSNR Improvement Using Different Prediction Coding

open access: yesTikrit Journal of Engineering Sciences, 2015
Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first

Optimal signal-to-noise ratio in stochastic time-delayed bistable systems

open access: yes, 2016
We study the optimal signal-to-noise ratio in a stochastic time-delayed bistable system. By using the small delay approximation, we transform the time-delayed system into stochastic nondelayed differential equations to obtain the ...

Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques [PDF]

open access: yes, 2014
In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and ...

Measurement of a Binaural Room Impulse Response with High Peak-to-Noise Ratio: [research data]

open access: yes, 2021
During their measurement, binaural room impulse responses (BRIRs) are impaired by equipment and background noise. The resulting noise floor might become perceptible when BRIRs are used for auralization purposes, i.e. by convolution with a dry source.

Zeros Removal with DCT Image Compression Technique

open access: yesJournal of Kufa for Mathematics and Computer, 2011
The discrete cosine transform (DCT) is a method for converting a signal into plain frequency components. It is extensively used in image compression. In this paper a new technique is proposed, namely ZRDCT (Zeros Removal with DCT) which is based on a ...

Improving the Quality of X-Ray Images of the Lungs of COVID-19 and Healthy Patients Using the Contrast Limited Adaptive Histogram Equalization (CLAHE) Method in Batam

open access: yesJournal of Electrical Engineering and Computer Sciences
X-ray imaging is a widely used technique for observing lung patients conditions. Compared to other radiographic methods, X-ray is more accessible, cost-effective, and commonly available in healthcare facilities. However, digital X-ray images often suffer

Thin Sectioning Improves the Peak Intensity and Signal-to-Noise Ratio in Direct Tissue Mass Spectrometry

open access: yesJournal of the Mass Spectrometry Society of Japan, 2006
Direct tissue analysis and imaging using mass spectrometry can extract a mass of information directly from complex biological samples. To carry out successful profiling and mapping of biomolecules, though, techniques for correct sample preparation are required. This article focuses on the influences of tissue thickness on mass spectra.
