传统的单粒子重建方法使用傅立叶或delta 函数基础来表示粒子密度图。我们提出了一个更灵活的算法，可以根据数据适应性地选择基础。由于基础适合数据，跟使用固定基础重建相比，分辨率和讯噪比(SNR) 都得到提高。而且，该算法自动遮盖粒子，使得粒子从背景中分离出来，无需在精制循环中使用专门滤波器或者蒙层。该算法是基于贝叶斯定理最大后验框架中表示，使用有效优化算法获得最大化。评估使用模拟和实际的低温电子显微镜数据，显示分辨率和 SNR 改进以及从背景中有效遮挡粒子。

A Multiple Selection based Control Tracker Often in developing designer and CAD related applications, one needs the functionality of moving and resizing selected objects around. MFC run-time provides one class i.e. CRectTracker that does something like this, but it has several shortcomings, the most important one being that it does not have functionality for multiple object selection and resizing. This article introduces a class, CControlTracker that does much more than what CRectTracker does

计算机图形图象学中的基本功能,如画直线,圆,Bezier曲线,B-样条曲线,KOCH曲线等.-Computer graphics images of the basic functions of school, painting a straight line, round, Bezier curves, B-spline curve, KOCH curve.

一个非常棒的二维等值线绘制程序，采用双三次曲面拟合算法，得到的等值线非常光滑，相比其它我所见的到的追踪等值线算法加平滑结果得到的等值线质量高出很多。-A great two-dimensional contour mapping procedures, the use of bicubic surface fitting algorithm, the contour lines to be very smooth, compared to the other I can see that the contour tracking algorithm increases the smoothing results are isogram much higher quality.

可绘制bizier curve, 无控制点数量限制,可用鼠标右键改变控制点位置,从而改变bizier curve的表现.双击鼠标左键可结束绘制.同时也可通过右侧指令修改或结束图像绘制.-to draw bizier curve, no limit of the number of the control points. and you can also change the position of the control points by using the right button of the mouse to change the behaver of the curve.double click the left button of the mouse to stop drawing. the program also support you to controll the drawing progress by the button left.
