Fusion Based Method for Wide Band Speech Reconstruction Over Legacy Telephone Networks [PDF]

Radioengineering
Public Switched Telephone Networks (PSTNs) are limited to Restricted Band (RB) speech in the 0-4 kHz range, which reduces speech quality compared to Wideband (WB) speech (0-8 kHz).

Speckle Noise Reduction in Optical Coherence Tomography Using Two-dimensional Curvelet-based Dictionary Learning

Journal of Medical Signals and Sensors, 2017
The process of interpretation of high-speed optical coherence tomography (OCT) images is restricted due to the large speckle noise. To address this problem, this paper proposes a new method using two-dimensional (2D) curvelet-based K-SVD algorithm for ...
