| Résumé : |
The problem of sampling rate alteration of deterministic two-dimensional signals is addressed on the basis of frequency domain description of the signal.
It is shown that the problem can be formulated in such a way that a solution can be obtained via filtering techniques known for one-dimensional signals.
Non-recursive implementations of such interpolation and decimation filters are investigated.
The resulting filter structures can potentially be implemented in parallel and/or pipelined architecture for fast real time applications.
Experiments with digitized images are also reported to demonstrate the performance of the designed interpolation and decimation filters. |
