Hello,
For image deblurring purposes, I am thinking of implement a wiener filter in FPGA. Is there a source code for this filter? Or maybe you can offer some useful ways about the implementation. Best Regards, |

Ahmm ... I hate to say it but, you're problem is ill-posed. Sure, a Weiner filter is the optimal filter out there. But, for those same reasons, it is impossible to create.
I've used adaptive filters for signal processing to approximate Weiner filter's. They work nicely in digital communications applications, where you can force the filter result to +/- 1. I'm not sure how you would do that for an image.
