An Improved Imaging Algorithm for Multi-Receiver SAS System with Wide-Bandwidth Signal
Remote Sensing, 2021 When the multi-receiver synthetic aperture sonar (SAS) works with a wide-bandwidth signal, the performance of the range-Doppler (R-D) algorithm is seriously affected by two approximation errors, i.e., point target reference spectrum (PTRS) error and ...

Synthetic aperture imagery for high-resolution imaging sonar
Frontiers in Marine Science, 2022 Synthetic aperture sonar (SAS) can provide high-resolution underwater images. Traditional fast imaging algorithms designed for multi-receiver synthetic aperture sonar (MSAS) are complex because the point target reference spectrum (PTRS) deduction and ...

Performance Bounds on Image Registration [PDF]
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006 Although a vast number of publications have appeared on image registration, performance analysis is usually performed visually and little attention has been given to statistical performance bounds. Such bounds can be useful in evaluating image registration techniques, determining parameter regions where more successful registration is possible, and ...

Back Projection Algorithm for Multi-Receiver Synthetic Aperture Sonar Based on Two Interpolators
Journal of Marine Science and Engineering, 2022 The back projection (BP) algorithm is characterized by its high performance for multi-receiver synthetic aperture sonar (SAS). For this reason, it is usually used to evaluate the imaging performance of Fourier-domain methods.

An objective structural and functional reference standard in glaucoma
Scientific Reports, 2021 The current lack of consensus for diagnosing glaucoma makes it difficult to develop diagnostic tests derived from deep learning (DL) algorithms. In the present study, we propose an objective definition of glaucomatous optic neuropathy (GON) using clearly
