We describe a 3D graphical interaction tool called an amplification widget that allows a user to control the position or orientation of an object at multiple scales. Fine and coarse adjustments are available within a single tool which gives visual feedback to indicate the level of resolution being applied. Amplification widgets have been included in instructional modules of The Optics Project, ...

We present a multi-resolution path planner and replanner capable of efficiently generating paths across very large environments. Our approach extends recent work on interpolation-based planning to produce direct paths through non-uniform resolution grids. The resulting algorithm produces plans with costs almost exactly the same as those generated by the most effective uniform resolution grid-ba...

The proposed technique extends conventional image morphing algorithms by offering additional control over the processing of the individual multi-resolutions that are used in the wavelet representation when moving from the source to the destination image. This gives the animator the possibility to introduce a disparity between the morphing of global and detail features that can lead to interesti...

We propose a novel, multi-resolution method to efficiently perform large-scale cloth simulation. Our cloth simulation method is based on a triangle-based energy model constructed from a cloth mesh. We identify that solutions of the linear system of cloth simulation are smooth in certain regions of the cloth mesh and solve the linear system on those regions in a reduced solution space. Then we r...

Image sensing is usually done with multiple sensors, like the RGB sensors in color imaging, the IR and EO sensors in surveillance and satellite imaging, etc. The resolution of each sensor can be increased by considering the images of the other sensors, and using the statistical redundancy among the sensors. Particularly, we use the fact that most discontinuities in the image of one sensor corre...
