A new type of ensemble filter is proposed, which combines an ensemble Kalman filter (EnKF) with the ideas of morphing and registration from image processing. This results in filters suitable for nonlinear problems whose solutions exhibit moving coherent features, such as thin interfaces in wildfire modeling. The ensemble members are represented as the composition of one common state with a spat...

The distributed compliance and smooth deformation field of compliant mechanisms provide a viable means to achieve shape morphing in many systems, such as flexible antenna reflectors and morphing aircraft wings. We previously developed a systematic synthesis approach to design shape morphing compliant mechanisms using Genetic Algorithm (GA). However, the design variable definition, in fact, allo...

Several authors have recently investigated the ability to compute intermediate views of a scene using given 2D images from arbitrary camera positions. The methods fall under the topic of image bused rendering. In the case we give here, linear morphing between two parallel views of a scene produces intermediate views that would have been produced by parallel movement of a camera. Hence, the tech...

Image morphing techniques can create a smooth transition between two images. However, one of the main weaknesses of the image morphing technique is that intermediate images in the transition often have physically incorrect shading such as highlights and shadows. Moreover, we cannot alter viewing and lighting conditions when creating the intermediate images. That is because those images are obta...

This paper introduces the geometric continuity equations of the closed planar polygons and gives the definition of a morphing with geometric continuity between two arbitrary planar polygons, including simple, non-3 and even degenerated polygons. A simple morphing technique based on linear interpolation of the geometric continuity equations is proposed. The closureness of the in-between polygons...

This paper presents the meta-morphing model and its practical application in an industry strength business intelligence solution. The meta-morphing model adds associations between measures and dimensions to a traditional multidimensional cube model, and thus facilitates a process where users are able to ask questions to a business intelligence (BI) system without the constraints of a traditiona...

Pipeline morphing is a simple but e ective technique for recon guring pipelined FPGA designs at run time. By overlapping computation and recon guration, the latency associated with emptying and re lling a pipeline can be avoided. We show how morphing can be applied to linear and mesh pipelines at both word-level and bit-level, and explain how this method can be implemented using Xilinx 6200 FPG...

An episodic unsupervised learning simulation using the Q-Learning method is developed to learn the optimal shape and shape change policy for a problem with four state variables. Optimality is addressed by reward functions based on airfoil properties such as lift coefficient, drag coefficient, and moment coefficient about the leading edge representing optimal shapes for specified flight conditio...
