Senior Member of the IEEE. Member Eta Kappa Nu, Tau Beta Pi.
Signal, image and image sequence processing, multidimensional digital signal processing, and computer vision. Current activities are in the processing and coding of images and image sequences, the application of local frequency and local scale (wavelet) representations to phonocardiogram-based cardiac diagnosis, and the application of local frequency representations in image processing and computer vision. Other research interests include segmentation and segmentation-based algorithms for image, image sequence and volumetric data processing and analysis.
