Using the order parameter of seismicity defined in natural time, we suggest a simple model for the explanation of B?th law, according to which a mainshock differs in magnitude from its largest aftersh
The Qinling orogen was formed as a result of the collision between the North and South China blocks. The Qinling orogen represents the location at which the southern and northern parts of the Chinese
Usually, GPS observation provides direct evidence to estimate coseismic displacement. However, GPS stations are scattered, sparse and cannot provide a detailed distribution of coseismic displacement.
Three identical model boxes were made from transparent plexiglass and angle iron. Using the method of sinking water and according to the sedimentary rhythm of saturated calcium carbonate(lime-mud) int
图像复原中通常假设图像在梯度域上是稀疏的,而非凸正则化方法会更加促进稀疏性.本文基于近年出现的几类非凸正则项,提出了泊松噪声下图像去模糊问题的几个非凸模型,发展了相应的高效求解算法,并研究了算法的收敛性;数值实验表明所提出的非凸模型可以增强图像在梯度域上的稀疏性,并优于一些现有的方法.
A 38.88 MHz time-stretch line-scan imaging system with parallel interleaving detection is experimentally demonstrated.Since only half-chromatic dispersion is used to stretch optical pulses for wavelen
Image registration is an old topic but has a new application in deep-sky imaging fields named live stacking. In this Letter, we propose a live stacking algorithm based on star detection, description,
Noise and the resonance characteristics of the focal plane array(FPA)are the most important factors that affect the performance of the optical readout infrared(IR)FPA imaging system.This Letter presen
Correlation imaging is attracting more and more at tent ion as a novel imaging technique taking advantage of the high-order coherence of light fields.To reconstruct an image oi the object,many frames
In this Letter, we propose an elemental image regeneration method of three-dimensional(3D) integral imaging for occluded objects using a plenoptic camera. In conventional occlusion removal techniques,
