对虚拟人图像数据作多种二维处理，包括图像几何变换、灰度增强、格式转换和压缩、图像配准和分割。
Many methods are used to finish VCH planar image processing, including image geometry transform, gray-scale enhancement format transition and compression , image registration and segmentation.
用这个算法可以处理的图像几何变换包括：图像旋转，图像变倍，图像剪切，以及图像翻转，镜像变换等。
In this algorithm, many basic geometric transformations of digital images are unified. These transformations include scaling, rotating, shearing, flipping, and mirroring, etc.
交互式数字图象的配准与镶嵌主要由二个步骤来完成：第一步是由人在显示屏幕上选择确定图像几何位置的控制点集，然后由此确定一幅图像几何变换使两幅图像在几何位置上配准。
Step one is to pick up the control point set which determines the geometric position of images, and then to derive a geometric transform for registering one image to another from those points.
