By introducing terms describing the random frequency modulation into optical Bloch equation, we have discussed spectral diffusion in such systems after a narrow band excitation .
通过在Bloch方程中增加描述对频率微扰的随机过程项{ω(t)},我们讨论了系统在窄谱带的光激发后的光谱扩散。
The eye sight principle of the model and control parameters of facula diffusion are expo
在个体轮廓探测环节,运用光斑扩散模型并对它的人眼视觉原理和光斑扩散中各项控制参数进行了深入的阐述和探讨,并在此基础上对它的单点扩散方式进行了改进,解决了此方式在对高屈曲截面纤维进行探测时不能探测到纤维全部轮廓的问题。
In allusion to the traditional contour tracing arithmetic which can only work on binary images and is not able to handle the interlinking phenomena among objects,this paper introduces facula diffusion model based on the principle of human vision,and illustrates its controlling parameters including approximation,closing,length-limiting and hit-rate.
针对传统的轮廓跟踪算法只能应用在二值图像上,无法处理目标间相互溶结的现象,提出基于人眼视觉原理的光斑扩散模型,并从逼近、贴近、径长突变和命中率4个方面阐述了其控制参数。
Based on mechanism of human sight,the facula diffusion method is advanced to detect individual cross-sections in the image and takes out the contours of them.
在人眼视觉机理的基础上,提出光斑扩散方法,用来探测图像中各个纤维截面并得到其轮廓线。
