The analysis of real-world conversational signal-to-noise ratios (SNRs) can provide insight into people's communicative strategies and difficulties guide the development hearing devices. However, measuring SNRs accurately is challenging in everyday recording conditions which only a mixture sound sources be captured. This study introduces method for accurate situ SNR estimation where speech sign...

We derive a detector function for quantum two-mode squeezing (QTMS) radars and noise that is based on the use of likelihood ratio (LR) test distinguishing between presence absence target. In addition to an explicit expression LR detector, we which approximates in limit where target small, far away, or otherwise difficult detect. When number integrated samples large, theoretical receiver operati...

An adaptive modification to the two-bit transform-based low-complexity block motion estimation approach is proposed. Initially, video frames are converted into two-bit representations using the two-bit transform (2BT), and binary block-based motion estimation is performed using these two bit-planes. Modification to the original 2BT-based motion estimation scheme is introduced by conditional loc...

In 1992 David Donoho has introduced the term denoising in connection with the adaptive nonlinear ...ltering in the discrete wavelets transform domain. Despite its advantages this method is not used yet in the communications ...eld. The goal of this paper is to propose a new denoising method, using another strategy for the threshold selection and another wavelets transform. This new discrete wav...

Background Single-shot (SSH) pulse sequences in CMR are beneficial for rapid image acquisition that is robust to motion, especially in arrhythmic patients or poor breath-holders. However, this fast scanning technique trades scan time for a lower signal-to-noise ratio compared to conventional multi-shot acquisitions. Here we propose a motion-compensated denoising technique that improves the imag...
