| 20110096227 | FRAME RATE CONVERSION WITH MOTION ESTIMATION IN A PLURALITY OF RESOLUTION LEVELS - Multiscale coefficients for each input video frame are distributed into K>1 groups. A first group of coefficients provides a representation of the frame at a first resolution level. For each integer k (1| 04-28-2011 | |
| 20100135400 | Processing Or Compressing N-dimensional Signals With Warped Wavelet Packets And Bandelets - A method and apparatus for processing or compressing an n-dimensional digital signal by constructing a sparse representation which takes advantage of the signal geometrical regularity. The invention comprises a warped wavelet packet transform which performs a cascade of warped subband filtering along warping grids of sampling points adapted to the signal geometry. It also comprises a bandeletisation which decorrelates the warped wavelet packet coefficients to produce a sparse representation. An inverse warped wavelet packet transform and an inverse bandeletisation reconstruct a signal from its bandelet representation. The invention comprises a compression system which quantizes and codes the bandelet representation, a decompression system, a restoration system which enhances a signal by filtering its bandelet representation, and a feature vector extraction system for pattern recognition applications of a bandelet representation. | 06-03-2010 |
| 20090278981 | METHOD AND APPARATUS FOR ROBUST SUPER-RESOLUTION VIDEO SCALING - A method and apparatus for scaling video images, which applies more particularly to techniques for converting video sequence formats and deinterlacing. The invention comprises a parameterized interpolation ( | 11-12-2009 |
