Transmitting high-quality neurophysiology video via the Internet is a challenging problem in telemedicine. We propose a novel video data processing and compression method based on the discrete wavelet transform (DWT). The DWT is utilized to decompose video frames into subframes, different bandwidth budgets are assigned to important and less important regions in each subframe, and several video encoders...
Transmitting high-quality video via the Internet is a challenging problem in distributed diagnosis system. We propose a content-based video data preprocessing scheme, which is adaptive to the video data acquired during intraoperative monitoring and can cascade with essentially any video codec. IOM video is first decomposed into temporal wavelet subband frames and motion compensation is incorporated...
The local maxima of the absolute values of the wavelet coefficients are used to measure the cross-correlation between a pair of input signals. Unlike the classical method which uses the cross-correlation coefficients where all data points are given equal weights, this approach utilizes the edge points only. These edge points are compared in pairs forming a cross-correlation vector whose length is...
