Abstract
A method and apparatus is disclosed herein for geometrical image representation and/or compression. In one embodiment, the method comprises creating a representation for image data that includes determining a geometric flow for image data and performing an image processing operation on data in the representation using the geometric flow.
Claims24
A method comprising:
- transforming image data into a first plurality of coefficients using a wavelet transform;
- generating predictions for coefficients and creating prediction errors corresponding to the predictions using geometric flow,
- generating information specifying the geometric flow;
- and
- encoding the prediction errors to create a compressed bitstream.
