As a result, multiple images of these background galaxies are distorted into long faint arcs — a simple lensing effect analogous to viewing distant street lamps through a glass of wine.
结果是这些背景星系的多重影像被扭曲成长而暗的弧——透镜效应的例子，类似于透过酒瓶底的玻璃看远处的街灯。
On the basis of the characteristics of the IR images, an algorithm of background estimation based on grayscale morphology with multiple structuring elements is presented.
该文在分析红外图像统计特征的基础上，提出了一种基于多结构元素灰度形态学的红外背景估计算法。
