In this article, we investigate the problem of tracking objects with unknown shapes using 3-D point cloud data. We propose a Gaussian process-based model to jointly estimate object kinematics, including position, orientation, and velocities, together shape for online offline applications. describe by radial function in 3-D, induce correlation structure via process. Furthermore, an efficient alg...

Many modeling domains can be meta modeled using the core UML structural concepts. When the user needs other specific forms generated from models in such domains, such as source code, model transformations should be defined. The author advocates a specification method for defining model translation that is visual, making specifications easier to create and modify.

This paper addresses the problem of tracking extended objects. Examples of extended objects are ships and a convoy of vehicles. Such kind of objects have particularities which pose challenges in front of methods considering the extended object as a single point. Measurements of the object extent can be used for estimating size parameters of the object, whose shape is modeled by an ellipse. This...

This extended abstract introduces the notion of ’ interval queries ’ on historical data for objects (here, called ‘object histories’) and explores a certain closure property. As for describing historical data for objects, we use our mathematical model introduced in our earlier paper. The major construct in the model is a ‘computation-tuple sequence scheme’ (abbreviated CSS), which specifies the...
