Wiener Filtering

Building the Cantata Workspace

1. Follow the same steps of the building the workspace for pseudo-inverse filtering lesson to find the restored image. Instead of implementing the pseudo-inverse filter procedure, implement the Wiener filter R(u) given in the previous page. Use the following operators: Magnitudes, Add, Divide, and Conjugate. Find the restored image for this case.
2. Use operator Wiener Filter to implement directly the Wiener filtering technique.

Exercises

• Modify the Wiener parameter in the Wiener Filter operator, visualize its effects and comment on the results.
