spatial_filter.py: lowpass_avg vs mean filter

[4restw...@gmail.com]

Hi All, I could use some clarification on the lowpass_avg filter in the spatial_filter.py script. I want to find the local mean of my image (i.e. the mean of all pixels in the kernel surrounding each pixel) and I believe this is already implemented in the lowpass_avg filter. Am I correct, or is the lowpass_avg filter different than a local mean filter?

Thanks!

That's correct, Forrest. 

We leverage existing python modules such as scipy.ndimage and skimage for the filtering, as an experimental utility tool. It will be no different from writing your own script to call those modules directly.
