利用标准显微镜图像，CellTrak 能提供迅速准确的对细胞进行追踪。

CellTrak 能同时对上百个细胞同时进行追踪，并能提供下列信息：

• 细胞质心的运动 (X,Y) vs. 时间
• 细胞方向 vs. 时间
• 细胞灰度信息 vs. 时间　　

CellTrak 能读取AVI文件，并进行分析。你可以将结果输出成ASCII文件，并用Excell或者其他软件进行分析.

特性

基本数学函数及三角函数: 可以使用，编辑多种函数来进行分析计算。并可以保存至特定文件 (.mts).

脚本语言 (用户程序) : 当用户使用数学函数来处理数据时，每一个步骤都可以被记录成脚本语句，并保存在脚本文件中。用户可以随时进行读取和修改。.

方向计算: 方向计算采用主成分分析法，更加精准.

读取并合并文件: 一次可以读取10个文件，不同文件的结果可以进行合并。.

边缘测定的方法:

• Binary Threshold - a greyscale threshold level determines an edge. This particular edge method requires dark objects on a light background. The other methods do not have this requirement.
• Canny Edge Detector - a well documented method which results in a single pixel edge and is able to find edges of light objects as well as dark objects. The smoothing algorithm is not currently used in conjunction with this method.
• Sobel Edge Detector - a template based edge detector which approximates the gradient of the pixel corresponding to the center of the template. Sobel uses two 3x3 matrices as a template.
• Kirsch Edge Detecto r - a template based edge detector which approximates the gradient of the pixel corresponding to the center of the template. Kirsch uses six 3x3 matrices as a template.
• Binary Threshold Smoothed Edges - The Binary Threshold images are smoothed automatically and then their edges are found. It provides the closest outlining of the greyscale dark on light images.
