High Resolution Surveillance Video Compression Using JPEG2000 Compression of Random Variables

This paper proposes a scheme for efficient compression of wide-area aerial video collectors (WAVC) data, based on background modeling and foreground detection using a Gaussian mixture at each pixel. The method implements the novel approach of treating the pixel intensities and wavelet coefficients as random variables. A modified JPEG 2000 algorithm based on the algebra of random variables is then used to perform the compression on the model. This approach leads to a very compact model which is selectively decompressed only in foreground regions. The resulting compression ratio is on the order of 16:1 with minimal loss of detail for moving objects.
