The imagealgebra description of the normal tracking algorithm is concise and inherently correspondent with the algorithm.
正常跟踪算法的图像代数描述是简明的，与算法是内在一致的。

The basic definitions and operators of this theory are given. In the end some grey scale image transformations based on the morphological grey scale imagealgebra are explained.
Because fractal dimension can not respond to the orientation of the gray level images, an image orientation Angle estimating method is proposed by basic knowledge of vector algebra.
