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...

Courtroom environments, which have been one of the last bastions of the oral tradition, are slowly morphing into cinematic display environments (Heintz, 2002). The persuasive oral rhetoric of lawyers is increasingly being replaced by compelling visual media displays presenting a range of digital evidence in a convincing and credible manner (Lederer, 2004; Schofield, 2007). There are a number of...

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...

In this paper, we first introduce a 3D morphing method for landmark-based volume deformation, using various scattered data interpolation schemes. Qualitative and speed comparisons are also made for different interpolation schemes. To efficiently render the volume morphing process, a new deformable volume rendering algorithm is presented. The algorithm renders the deformed volume directly withou...

In this paper, we propose a new multiresolution-based shape representation for 3D mesh morphing. Our approach does not use combination operations that caused some serious problems in the previous approaches for mesh morphing. Therefore, we can calculate a hierarchical interpolation mesh robustly using two types of subdivision fitting schemes. Our new representation has a hierarchical semiregula...

In this work we propose a novel approach to curve morphing. We represent curves by strings, i.e. sequences of symbols. The curve morphing problem is formulated as that of computing a weighted mean of two strings, which is then solved by a corresponding algorithm recently reported in the literature. Although only 2D curves are used in our experiments, the approach is applicable to curves in any ...

A micro air vehicle is a flight system being designed for operation within urban environments. Such vehicles are small and highly agile but often have limited control authority. This paper investigates the use of morphing as an effector to provide control authority. Simple mechanisms for morphing are designed to twist the wings of a 24 in vehicle and to curl the wings of a 12 in vehicle. Flight...

Strain fields provide a method of deformation measurement based on physics. Using these as a tool, we can analyze deformation of objects in a measurable way. We have developed a new morphing technique based on strain field interpolation. Shape shaking and squeezing, which often happen when using linear interpolation for morphing, do not arise in our approach. We have also developed a new method...

A new multiscale voice morphing algorithm using radial basis function (RBF) analysis is presented in this paper. The approach copes well with small training sets of high dimension, which is a problem often encountered in voice morphing. The aim of this algorithm is to transform one person’s speech pattern so that it is perceived as if it was spoken by another speaker. The voice morphing system ...

This paper presents a new voice morphing method which focuses on the continuity of phonological identity overall interand extra-polated regions. Main features of the method are 1) to separate the characteristic of vocal tract area resonances from that of vocal cord waves by using AR-HMM analysis of speech, 2) interpolation in a log vocal tract area function domain and 3) independent morphing fo...
