Visual interpretation of hand gestures for human-computer interaction: A review

by Vladimir I. Pavlovic, Rajeev Sharma, Thomas S. Huang - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 1997
"... The use of hand gestures provides an attractive alternative to cumbersome interface devices for human-computer interaction (HCI). In particular, visual interpretation of hand gestures can help in achieving the ease and naturalness desired for HCI. This has motivated a very active research area conc ..."

concerned with computer vision-based analysis and interpretation of hand gestures. We survey the literature on visual interpretation of hand gestures in the context of its role in HCI. This discussion is organized on the basis of the method used for modeling, analyzing, and recognizing gestures. Important

R.: Semi-quantitative stability analysis constrains saturation levels in metabolic networks

by M. Hafner, R. Steuer - In: Proc. Int. Workshop on Comput. Syst. Biol , 2009
"... Recently structural kinetic modeling has been proposed as an intermediary approach between a full kinetic descrip-tion of metabolic networks and a static constrained-based analysis of them. It extends the null-space analysis by a local stability analysis yielding a parametrization of the Jacobian in ..."

Ecologically Meaningful Transformations For Ordination Of Species Data

by Pierre Legendre, Eugene D. Gallagher
"... This paper examines how to obtain species biplots in unconstrained or constrained ordination without resorting to the Euclidean distance (used in principal component analysis, PCA, and redundancy analysis, RDA) or the chi-square distance (preserved in correspondence analysis, CA, and canonical corre ..."

Algorithms and applications for approximate nonnegative matrix factorization

by Michael W. Berry, Murray Browne, Amy N. Langville, V. Paul Pauca, Robert J. Plemmons - Computational Statistics and Data Analysis , 2006
"... In this paper we discuss the development and use of low-rank approximate nonnegative matrix factorization (NMF) algorithms for feature extraction and identification in the fields of text mining and spectral data analysis. The evolution and convergence properties of hybrid methods based on both spars ..."

Instruction level power analysis and optimization of software

by Vivek Tiwari, Sharad Malik, Andrew Wolfe, Mike Tien-chien Lee - Journal of VLSI Signal Processing , 1996
"... Abstract. The increasing popularity of power constrained mobile computers and embedded computing applications drives the need for analyzing and optimizing power in all the components of a system. Software constitutes a major component of today's systems, and its role is projected togrow even fu ..."

This paper describes an alternative, measurement based instruction level power analysis approach that provides an accurate and practical way of quantifying the power cost of software. This technique has been applied to three commercial, architecturally di erent processors. The salient results

Analysis of speaker adaptation algorithms for HMM-based speech synthesis and a constrained SMAPLR adaptation algorithm

by Junichi Yamagishi, Takao Kobayashi, Senior Member, Yuji Nakano, Katsumi Ogata, Juri Isogai - IEEE Trans. Audio Speech Lang. Process , 2009
"... Abstract—In this paper, we analyze the effects of several factors and configuration choices encountered during training and model construction when we want to obtain better and more stable adaptation in HMM-based speech synthesis. We then propose a new adaptation algorithm called constrained structu ..."

PLSA-based Image Auto-Annotation: Constraining the Latent Space

by Florent Monay, Daniel Gatica-Perez - In Proc. ACM Int. Conf. on Multimedia , 2004
"... We address the problem of unsupervised image auto-annotation with probabilistic latent space models. Unlike most previous works, which build latent space representations assuming equal relevance for the text and visual modalities, we propose a new way of modeling multi-modal co-occurrences, constrai ..."

-occurrences, constraining the definition of the latent space to ensure its consistency in semantic terms (words), while retaining the ability to jointly model visual information. The concept is implemented by a linked pair of Probabilistic Latent Semantic Analysis (PLSA) models. On a 16000-image collection, we show

NON-NEGATIVE MATRIX FACTORIZATION BASED ON ALTERNATING NON-NEGATIVITY CONSTRAINED LEAST SQUARES AND ACTIVE SET METHOD

"... The non-negative matrix factorization (NMF) determines a lower rank approximation of a ¢¤£¦¥¨§�©���� �� � matrix where an ������������������ � interger is given and nonnegativity is imposed on all components of the factors applied to numerous data analysis problems. In applications where the compone ..."
