I am trying to use FIR filter (opensource codes from iowa hills software) as low pass filter, kaiser window, to filter 2D image.

Does someone can guide me that how can I do that? I am able to obtain FIRCoeff() as filter coefficients. Not sure how to use it on a 2D image.

My goal is to filter high-frequency noise in my 2D image.

    $\begingroup$ Which platform will you implement the filtering in? Or do you just need a theoretical answer ? $\endgroup$ – Fat32 Jul 7 '17 at 21:09
