超细颗粒布朗运动模糊图像位置信息的提取方法研究

RESEARCHING THE METHOD OF DRAWING PARTICLE'S POSITION INFORMATION FROM INDISTINCT MOVEMENT IMAGE OF SUBMICRON BROWNIAN PARTICLES

本文详细讨论了经计算机图象增强处理后，在时刻ｔ布朗颗粒模糊图象位置信息的获取方法：１．区域生长法获取颗粒模糊图象在时刻ｔ的灰度重心位置信息；２．外切矩形法获取颗粒在时刻ｔ的灰度重心位置信息。同时，还对两种方法的优劣做了详细的叙述，并通过实验证明了两种方法相结合得到处理结果的正确性。

Directed to the system,the drawing method of particle's position information at t time from indistinct movement image (by computer enhancing)of submicron Brownian particles is discussed in detail.This paper contains:1.Aera growing method to get the center position information of gray at t time from indistinct particle's image,2. External tangent tectangle method to pick up the center position information of gray at t time.Meanwhile,the advantages and disadvantages of the two methods are described clearly, and the correctness of processing results is proved through experiments of combining to two methods.
