International Conference on Acoustics, Speech, and signal processing (ICASSP)
作者: Adriane Swaim Durey Mark A. Clements Center for Signal and Image Processing Geogria Institute of Technology School of Electrical and Computer Engineering Atlanta GA USA
The amount of digitized music stored on personal computers and available on the Internet is growing at a rapid rate. To address the access problem that this creates, we explore adapting HMM-based wordspotting techniqu... 详细信息

IEEE International Conference on image processing
作者: Joohee Kim R.M. Mersereau Y. Altunbasak Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA
This paper presents a coordinated multiple-substream unequal error protection and error concealment algorithm for SPIHT-coded bitstreams transmitted over lossy channels. In the proposed scheme, we divide the video seq... 详细信息

Asilomar Conference on signals, Systems & computers
作者: P.S. Hong M.J.T. Smith Center for Signal and Image Processing Georgia Institute of Technology School of Electrical and Computer Engineering Atlanta GA USA
Several multidimensional filter banks are described and analyzed for the purpose of processing hyperspectral data. A new octave band directional filter bank (OBDFB) is introduced that is able to isolate directional ba... 详细信息

IEEE National Conference on Radar
作者: R.K. Hersey M.A. Richards J.H. McClellan Center for Signal & Image Processing School of Electrical & Computer Engineering Georgia Institute of Technology Atlanta GA USA School of Electrical & Computer Engieering Georgia Institute of Technology Atlanta GA USA
With advances in Doppler weather radar, severe storm and tornado detection has improved greatly. However, the resolution limitations of deployed radar systems can still limit severe storm detection. In the case of lar... 详细信息

IEEE Digital signal processing Workshop
作者: Yeo-Sun Yoon L.M. Kaplan J.H. McClellan Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA CTSPS Department of Engineering Clark Atlanta University Atlanta GA USA
Recently, we proposed the pruned fast beamformer that is able to detect coherent signals during beamforming. The fast beamformer is a multistage approximation to delay and sum beamforming. Using a coherent signal dete... 详细信息

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)
作者: Qian Du Hsuan Ren Chein-I Chang Department of Electrical Engineering and Computer Science Texas A and M University Kingsville TX USA Edgewood Chemical and Biological Center US Army MD USA Remote Sensing Signal and Image Processing Laboratory Department of Computer Science and Electrical Engineering University of Maryland Baltimore MD USA
Orthogonal subspace projection (OSP) and generalized likelihood ratio test (GLRT) have shown success in hyperspectral image classification. The OSP is derived by maximizing signal-to-noise ratio (SNR) resulting from a... 详细信息

2nd Annual International Symposium on Music Information Retrieval, ISMIR 2001
作者: Durey, Adriane Swalm Clements, Mark A. Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology AtlantaGA30332 United States
As we acquire more digitized copies of musical recordings, it becomes increasingly necessary to have the assistance of a computer in sorting through the information that it stores. In this paper, we propose a new syst... 详细信息

Conference on computer Vision and Pattern Recognition (CVPR)
作者: A.U. Batur M.H.I.I.I. Hayes Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA
In this paper, we present a segmented linear subspace model for face recognition that is robust under varying illumination conditions. The algorithm generalizes the 3D illumination subspace model by segmenting the ima... 详细信息

IEEE National Conference on Radar
作者: M.C. Cobb J.H. McClellan Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA
A variation on the quadtree algorithm for ultra-wideband, wide-angle (UWB-WA) SAR imaging that uses the /spl omega/-k algorithm for final stage focusing is introduced. Several signal processing techniques appropriate ... 详细信息

International Conference on Information Technology: Coding and Computing (ITCC)
作者: F. Alturki R. Mersereau Department of Electrical and Computer Engineering Center of Signal and Image Processing Georgia Institute of Technology Atlanta GA USA
Data hiding in multimedia is the process of secretly embedding information into data sources such as image, video, or audio signals without changing the perceptual quality of the data source. We present a novel blind ... 详细信息
