The whole frame used in this paper is that , first , by using video card , we get a series of b - scan images , then delete the noise in this images . secondly , draw the outline of interesting object in each image by manual , through clicking mouse on screen . thirdly , reconstruct 3d - image using 2d contour 本文图像处理采用的总体方案是:首先,运用图像采集卡从b超仪获取一系列超声断面图像,然后对超声图像进行去噪预处理,再通过人机交互的方式,手工勾画出各层图像中感兴趣目标的轮廓线,并运用三维重构技术进行三维重构,最后运用opengl将三维图像显示出来。
And based on these theories and methods , an image retrieval by region units is presented . first , when scan image orderly , continuously incorporate neighbor similar pixels in color and get several region units . then , write the values of color , shape , and position into database 基于这些理论与方法,提出了一种以区域块为单位的图像检索方法,其基本思想是在顺序扫描图像的同时,运用递归算法不断合并四邻域相似颜色象素得到若干区域块,同时记录下区域块的颜色、形状和位置等量化特征。
Discussed the optical imaging principle of laser confocal scanning microscopic imaging system whose important character is high plane resolution and high depth resolution . analyzed the controlling technique of scanning imaging . according to the different needs for laser confocal scanning microscopy and gene - chip scanner , two kinds of scanning methods , optics scanning and object scanning , are presented 讨论了激光共聚焦扫描显微成像系统的光学原理及其成像的重要特点,即激光共聚焦扫描显微成像系统不仅具有高的平面分辨率而且具有很高的深度分辨率;分析了系统的扫描成像控制技术,根据激光共聚焦扫描显微镜系统和基因芯片扫描仪的不同需要提出了两种扫描方式,即光学扫描方式和物体扫描方式,指出了两种扫描方式的优缺点,并对各自的成像非线性畸变问题进行了探讨,提出了解决方案。
