Noise reduction algorithm

[tinjamin]

Hi,

I have tried to find an algorithm to reduce noise from images, but all that I have found are just some theoretical papers.

I`m not sure if it can be done with a convolution matrix? The ones I`ve tried just blur the image.

Does anybody have any experience on this?

Regards,

Tim

There are several noise reducion algorithims.

They are:

Convolution
Binomial Smooting
Butterworth Lowpass Filtering
Inverse Filter
Ideal Lowpass Filtering
Gausian Smoothing
Median Filtering
Nonlinear Diffusion

There is quite a bit of info on each on the web including several libraries with source code.
