    DCT-based motion estimation
    Download  www.cspl.umd.edu
    —We propose novel discrete cosine transform (DCT) pseudophase techniques to estimate shift/delay between two onedimensional (1-D) signals directly from their DCT coefficients by...

    On the Complexity of Decoding Lattices Using the Korkin-Zolotarev Reduced Basis
    Download  www.cst.uwaterloo.ca
    —Upper and lower bounds are derived for the decoding complexity of a general lattice L. The bounds are in terms of the dimension n and the coding gain of L, and are obtained ba...

    A full-featured, error-resilient, scalable wavelet video codec based on the set partitioning in hierarchical trees (SPIHT) algor
    Download  www.cipr.rpi.edu
    Compressed video bitstreams require protection from channel errors in a wireless channel. The threedimensional (3-D) SPIHT coder has proved its efficiency and its real-time capabi...

    New architecture for dynamic frame-skipping transcoder
    Download  www.eie.polyu.edu.hk
    Abstract--Transcoding is a key technique for reducing the bitrate of a previously compressed video signal. A high transcoding ratio may result in an unacceptable picture quality wh...

    Object tracking using the Gabor wavelet transform and the golden section algorithm
    14 years 11 months ago
    Object tracking using the Gabor wavelet transform and the golden section algorithm
    Download  www2.ece.ohio-state.edu
    This paper presents an object tracking method for object-based video processing which uses a two-dimensional (2-D) Gabor wavelet transform (GWT) and a 2-D golden section algorithm....
