Abstract
A method and apparatus for enhancing a d-dimensional digital signal by taking advantage of regular geometrical structures. The invention comprises a multiscale redundant grouping lifting (), which iteratively computes grouping arrays and bandelet signals with a redundant grouping lifting. A second step makes an enhancement () of bandelet signals. A third step is an inverse multiscale redundant grouping lifting () which iteratively updates an enhanced average signal with an inverse redundant grouping lifting that takes in input enhanced bandelet signals. It outputs an enhanced signal. The invention also comprises a subband grouping bandelet enhancement which incorporates a subband decomposition and reconstruction. It includes a super-resolution process which increases the signal resolution by computing an output enhanced signal on an output sampling grid that is larger than the input sampling grid. It also includes restoration systems that invert degradation operators with grouping bandelet enhancements.
