METHOD AND DEVICE FOR ENCODING/DECODING A DISPLACED FRAME DIFFERENCE |
摘要 |
<p>The present invention provides a method (100, 700), device (400, 800) and microprocessor (500) for performing a computationally efficient iterative expansion of a displaced frame difference, DFD, image over a predetermined dictionary of modulated Gaussian functions for the purposes of video compression. The iterative expansion described in this invention decomposes the DFD image into a set of coefficients which represent the perceptually important areas of a video frame in a compact way. The resulting method, device and microprocessor serve to provide a means for very low bit rate coding/decoding of a video sequence.</p> |
