Functional Gabor single-frame or multi-frame generator multipliers are the matrices of function entries that preserve Parseval generators. An interesting and natural question is how to characterize all such multipliers. This has been answered for several special cases including case generators in two dimensions one-dimension. In this paper we completely with respect separable time-frequency lat...

Multiresolution models represent objects providing a wide range of resolutions or levels of detail (LOD). Efficient storage and retrieval of the different LODs is necessary in order to achieve interactive visualization. In this paper we present a data structure and algorithm that, using a Multiresolution Ordered Meshes (MOM) representation, allow us to extract uniform resolution LODs exploiting...

This paper demonstrates a novel method to generate house designs completely from 3/4” plywood sheets. A shape grammar routine is employed to divide an initial solid shape into constructible components for fabrication by CNC wood routing. The paper demonstrates programmable functions that can be performed using CAD scripting. Future goals for the grammar are to develop CAD programs for digital f...

Amidst the recent crazes for emerging technologies like speech recognition and biometrics, speaker recognition is slowly reaching the maturity to be deemed practical in many diierent applications. This paper presents new approaches for text-independent speaker recognition. The performances of the model-based algorithm presented concurrently at the ICASSP'98 conference and the frame-based algori...

Quantitative motion analysis from echocardiography is an important yet challenging problem. We develop a motion estimation algorithm for echocardiographic image sequences based on diffeomorphic image registration in which the velocity field is spatiotemporally smooth. The novelty of this work is that instead of optimizing a functional of velocity field which consists of similarity metrics betwe...

We present a system for rendering 3D animations in the style of line drawings. We use a highly parameterized line model in order to determine the appearance of a line. This model allows us to render characteristic line deviations that remain—in contrast to existing non-photorealistic rendering systems—frame coherent. Other inconsistencies which result from intersection and visibility changes du...

This paper describes the general properties of the system submitted to the MIREX 2010 tempo estimation tasks.

Autonomous navigation of indoor unmanned aircraft systems (UAS) requires accurate pose estimations usually obtained from indirect measurements. Navigation based on inertial measurement units (IMU) is known to be affected by high drift rates. The incorporation of cameras provides complementary information due to the different underlying measurement principle. The scale ambiguity problem for mono...

Frame theory is a powerful tool in the domain of signal processing and communication. Among its numerous configurations, the ones which have drawn much attention recently are Equiangular Tight Frames(ETFs) and Grassmannian Frames. These frames both have optimality in coherence, thus bring robustness and optimal performance in applications such as digital fingerprint, erasure channels, and Compr...
