5th IEEE International Symposium on Biomedical Imaging
作者: Bai, Lijun Qin, Wei Liang, Jimin Tian, Jie Xidian Univ Life Sci Res Ctr Xian Peoples R China Chinese Acad Sci Inst Automat Med Image Proc Grp Beijing 100864 Peoples R China
Most clustering algorithms in fMRI analysis implicitly require some nontrivial assumption on data structure. Due to arbitrary distribution of fMRI time series in the temporal domain, such analysis may mislead and limi... 详细信息

32nd IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Kim, Joehwan Shim, Kwang-Hyun Choi, Seungiin ETRI Digital Content Res Div Taejon South Korea POSTECH Dept Comp Sci Pohang South Korea
In this paper we present a kernel method for data clustering, where the soft k-means is carried out in a feature space, instead of input data space, leading to soft kernel k-means. We also incorporate a geodesic kerne... 详细信息

IEEE International Conference on Image Processing (ICIP 2006)
作者: Cozar, J. R. Guil, N. Gonzalez-Linares, J. M. Zapata, E. L. Univ Malaga Dept Comp Architecture E-29071 Malaga Spain
In this paper a technique for video cataloging based on logo detection is shown. No a priori knowledge about shape or spatial-temporal location of logos is assumed. The method implements a new algorithm for on-line lo... 详细信息

14th IEEE/SP Workshop on Statistical Signal Processing
作者: Ahmadi, Abbas Karray, Fakhri Kamel, Mohamed Univ Waterloo Pattern Anal & Machine Intelligence Lab Waterloo ON N2L 3G1 Canada
A new approach for clustering phoneme data is proposed. The proposed approach mimics the behavior of biological swarms seeking food located in different places. Best locations for finding food are in dense areas and, ... 详细信息

32nd IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Kim, Yong-Deok Choi, Selingiin POSTECH Dept Comp Sci Seoul South Korea
Nonnegative matrix factorization (NMF) is a widely-used method for multivariate nonnegative data analysis, due to its ability to learn a parts-based representation. However, the standard NMF algorithm does not always ... 详细信息
