Description: 全数字摄影测量系统 VirtuoZo 具有以下特点：
全软件化设计：VirtuoZo 是一个全软件化设计、功能齐全和高度智能化的全数字摄影测量系统。
高度自动化：影像的内定向、相对定向、影像匹配、建立DEM、由DEM提取等高线和制作正射影像等操作，基本上不需要人工干预，可以批处理地自动进行。
高效率：相对定向只需1-2分钟，匹配同名点的速度达到每秒500点以上。
灵活性：系统提供了“自动化”和“交互处理”两种作业方式。用户可以根据具体情况灵活选择。
通用性：系统不仅能基于航空影像生产从1:50,000到1:500各种比例尺的4D产品（DEM、DOM、DLG和DRG），还能处理近景影像、中等分辨率的卫星影像（如：SPOT、TM等卫星影像）、IKONOS卫星影像、QuickBird 卫星影像和可量测数码相机影像。
采集三维基础地理信息的理想平台：基于 MicroStation 软件开发的数字测图接口模块 Vlink，实现了 VirtuoZo 和 MicroStation 之间的实时数据通讯。他在 MicroStation 基本功能的基础上针对测图生产的实际情况增加了新功能，形成了一个采编一体化的数字测图系统。
-VirtuoZo full digital photogrammetric system has the following characteristics:
full software design: VirtuoZo is a full software design, functional and highly intelligent full digital photogrammetry system.
highly automated: within the image orientation, relative orientation, image matching, the establishment of DEM, contour lines extracted from the DEM and orthophoto production and other operations, with almost no human intervention, can be batch to be automated.
high efficiency: the relative orientation only 1-2 minutes, matching the speed of the same name point more than 500 points per second.
Flexibility: The system provides "automatic" and "interactive process" of two practices. Users the flexibility to choose according to specific circumstances.
versatility: The system can not only production based on aerial images of various scales from 1:50,000 to 1:500 of the 4D product (DEM, DOM, DLG and DRG), can handle close-

Description: Multispectral remotely sensing imagery with high
spatial resolution, such as QuickBird, IKONOS satellite
imagery or Aerial imagery, especially in urban scenes, often
perform spectral variations and rich details within a category,
resulting in a poor accuracy of classification. To seek an efficient
solution, this paper presents a non-parametric and variational
multiple level set model by a joint use of Aerial image and two
products, digital terrain model (DTM) and digital surface model
(DSM), directly or indirectly derived raw LiDAR (Light
Detection And Ranging) 3D point cloud data. Proposed model is
to minimize an energy function. The energy includes two terms.
First term is mainly image-based energy which introduces Parzen
Window density estimation technique in the multiple level set
framework. To make up the disadvantages-Multispectral remotely sensing imagery with high
