Adaptive Image Thresholding Based on the Peak Signal-to-noise Ratio
Research Journal of Applied Sciences, Engineering and Technology, 2014 L'objectif de cette recherche est d'améliorer un algorithme de seuillage basé sur le rapport de bruit du signal de crête. Le seuillage est une étape critique dans la reconnaissance des formes et a un effet significatif sur les étapes ultérieures des applications d'imagerie.

Robust image transmission performed by SPIHT and turbo-codes [PDF]
Serbian Journal of Electrical Engineering, 2008 This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are

Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]
, 2020 One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...

Signal-to-noise ratio in diffusion-ordered spectroscopy: how good is good enough? [PDF]
Magnetic Resonance, 2021 Diffusion-ordered NMR spectroscopy (DOSY) constructs multidimensional spectra displaying signal strength as a function of Larmor frequency and of diffusion coefficient from experimental measurements using pulsed field gradient spin or stimulated echoes ...

Evaluation of peak-picking algorithms for protein mass spectrometry [PDF]
, 2011 Peak picking is an early key step in MS data analysis. We compare three commonly used approaches to peak picking and discuss their merits by means of statistical analysis. Methods investigated encompass signal-to-noise ratio, continuous wavelet transform,

Frequency-Selective PAPR Reduction for OFDM [PDF]
, 2019 We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...
