针对经典视觉背景提取算法长时间存在鬼影、动态背景导致的高频噪声以及背景模型误更新等问题,提出一种改进的视觉背景提取算法。该算法将原始图像分割为若干个超像素区域,在超像素分割区域,对视觉背景提取算法检测结果进行像素点再分类,在目标检测的初始阶段实现鬼影信息的准确检测,并更新鬼影区域像素点的背景模型,从根本上解决了全局范围内鬼影检测的难题。根据运动目标的超像素对前景目标内的空洞进行快速纠正,实现前景目
本文报道了一种简单的测量光脉冲强度的时空分布方法。用此方法得到Cu/CuBr和Ph激光的具有立体感的光脉冲形状,它包括了光脉冲结构的一些细节,以及光脉冲的瞬时发散度。

Published 16 January 2012 Stroke and heart attack, which could be led by a kind of cerebrovascular and cardiovascular disease named as atherosclerosis, would seriously cause human morbidity and mortality. It is important for the early stage diagnosis and
We report a photoluminescence observation of the coupling of donor-bound excitons and longitudinal optical phonons in high-quality ZnO crystals at 5 K. The first-order phonon Stockes line of donor-bound excitons exhibits a distinct asymmetric line shape w
Contrast agents are attracting a great deal of attention in photoacoustic imaging. Here we introduce an exogenous contrast agent that provides high photoacoustic signal amplitude at the near-infrared wavelength. Our agents consist of Indocyanine green (IC
硏究与发展高速光探测器是为了探测由激光器、发光二极管射出的几毫微秒以下的短光脉冲，现在它被广泛用于使用激光器和发光二极管的光通信装置上。高速光探测器有光电倍增管和使用半导体的光电二极管、雪崩光电二极管。光电倍增管是利用外光电效应和二次电子倍增效应的具有内放大作用的光探测器。

Laser pulses with energy of ~10 μJ are generated at 46.9 nm on the 3p-3s transition of the Ne-like Ar by a fast capillary discharge setup in both 3- and 4-mm channels. The dependence of the laser output pulse energy on the pressure of Ar gas is measured f
