Combining visual shape-capturing and vision-based object manipulation without intermediate manual interaction steps is important for autonomic robotic systems. In this work we introduce the concept of such a vision system closing the chain of shape-capturing, detecting and tracking. Therefore, we combine a laser range sensor for the first two steps and a monocular camera for the tracking step. ...

Internal boundaries and interfaces are an important part of many uid and solid modeling problems. Front Tracking contains a general interface framework, closely related to the non-manifold geometry used in CAD solid modeling packages, to support numerical simulation of such uid problems. It can thus be considered to be a systematic application of the ideas of computational geometry to computati...

A new and simplified front tracking algorithm has been developed as an aspect of the extension of this algorithm to three dimensions. Here we emphasize two main results: (1) a simplified description of the microtopology of the interface, based on interface crossings with cell block edges, and (2) an improved algorithm for the interaction of a tracked contact discontinuity with an untracked shoc...

A method for extracting information (or knowledge) about the nature of a signal is presented, this is achieved by tracking the dynamics of the mixing parameter within a hybrid filter rather than the actual filter performance. Implementations of the hybrid filter for tracking the nonlinearity and the sparsity of a signal are illustrated and simulations on benchmark synthetic data in a prediction...

A simple particle tracking technique based on an Eulerian-Lagrangian finite element approach was used to solve the solute transport equation. The method introduces only one moving particle to track each concentration front continuously forward in one-dimensional transport problems. At each time step, all element nodes are taken as moving particles along the characteristic path. The single-step ...

We present the first triangle mesh-based technique for tracking the evolution of general three-dimensional multimaterial interfaces undergoing complex topology changes induced by deformations and collisions. Our core representation is a non-manifold triangle surface mesh with material labels assigned to each half-face to distinguish volumetric regions. We advect the vertices of the mesh in a La...

As for multi-uninhabited aerial vehicle cooperative fire fighting problem, a multiuninhabited aerial vehicle cooperative control method was proposed based on consensus algorithm. multi-uninhabited aerial vehicle cooperative control problem was divided into two steps: 1) a multi-uninhabited aerial vehicle arrival simultaneous control strategy under influence of wind field based on consensus algo...
