Numerical Simulation and Analysis of the Spiky Sea Clutter from the Sea Surface With Breaking Waves
Yiwen Wei,Lixin Guo,Juan Li +2 more
TL;DR: In this paper, the authors presented a feasible and efficient scattering model of the time-varying complex sea surface process to describe the phenomena of sea spikes as well as the super events from realistic sea clutter, wedges are posited on the two-scale sea surface to provide an approximate simulation of the breaking waves.

Guo Lixin,Xu Runwen,Chai Shuirong,Yiwen Wei,Li Ke +4 more
- 04 Sep 2013
TL;DR: In this paper, a medium rough surface finite element electromagnetic simulation method based on integral boundary is proposed, which is more easily used for simulating inhomogeneous medium electromagnetic problems than the integral equation class methods, can improve electromagnetic simulation precision compared with the approximate absorbing boundary, and can be used for acquiring the electromagnetic scattering parameters of medium rough surfaces unbounded area problems.

Interval Type-2 Fuzzy Logic for Semisupervised Multimodal Hashing
TL;DR: The proposed label estimation method has been experimentally proven to be more feasible for a multilabeled MIRFlickr data set in a hash lookup task and can still compete with the worst compared supervised one.

Higher order method of moments for bistatic scattering from 2d pec rough surface with geometric modeling by nurbs surface
TL;DR: In this paper, a higher order method of moments (HMOM) was proposed to calculate the bistatic scattering from two-dimensional (2D) perfectly electric conducting (PEC) rough surface.
Learning Decorrelated Hashing Codes With Label Relaxation for Multimodal Retrieval
Dayong Tian,Yiwen Wei,Deyun Zhou +2 more
TL;DR: A minimum correlation regularization (MCR) for multimodal hashing is proposed rather than being imposed on projection matrix, MCR is imposed on a differentiable function which approximates the binarization.
