• Bayesian Spherical Wavelet Shrinkage: Applications to Shape Analysis 

      Le Faucheur, Xavier; Vidakovic, Brani; Tannenbaum, Allen R. (Georgia Institute of Technology, 2007)
      Multiscale analysis has become a very useful tool in image processing and computer vision. Our work is motivated by the need to efficiently represent 3D shapes that exhibit a spherical topology. This note presents a wavelet ...
    • Classification of High Frequency Pupillary Responses using Schur Monotone Descriptors in Multiscale Domains 

      Shi, Bin; Moloney, Kevin P.; Pan, Ye; Emery, V. Kathlene; Vidakovic, Brani; Jacko, Julie A.; Sainfort, François (Georgia Institute of Technology, 2004-09-21)
      This paper addresses the problem of classifying users with different visual abilities based on their pupillary response data while performing computer-based tasks. Multiscale Schur Monotone (MSM) summaries of high frequency ...
    • Denoising Ozone Concentration Measurements with BAMS Filtering 

      Katul, Gabriel G.; Ruggeri, Fabrizio; Vidakovic, Brani (Georgia Institute of Technology, 2001)
      We propose a method for filtering self-similar geophysical signals corrupted by an antoregressive noise using a combination of non-decimated wavelet transform and a Bayesian model. In the application part, we consider ...
