Latest Patents
Jérôme Kalifa holds a patent for "Processing or compressing n-dimensional signals with warped wavelet packets and bandelets." This invention presents a method and apparatus for processing or compressing n-dimensional digital signals by constructing a sparse representation that leverages the geometrical regularity of the signal. The invention includes a warped wavelet packet transform that performs a cascade of warped subband filtering along warping grids of sampling points tailored to the signal geometry. Additionally, it features bandeletisation, which decorrelates the warped wavelet packet coefficients to yield a sparse representation. The system also encompasses an inverse warped wavelet packet transform and an inverse bandeletisation to reconstruct a signal from its bandelet representation. Furthermore, it includes a compression system that quantizes and codes the bandelet representation, a decompression system, a restoration system that enhances a signal by filtering its bandelet representation, and a feature vector extraction system for pattern recognition applications.
