Hello, users!
I want to blur my binary files having a numerical value for each grid point.
(e.g., seismograms of seismic exploration, having little low frequency
component and much noise.)
I thought that the function, fspecial.m could help me.
'Gaussian blur', one of 'fspecial.m' is like below..
http://www.mathworks.co.kr/help/toolbox/images/ref/fspecial.html
But 'fspecial.m' looks like a tool for images not binary files.
Does 'fspecial' works for binary files?
Or is there any way to convert images (after blurred by 'fspecial') to
binary files?
Though I tried applying low-pass filtering using filtfilt or filter to my
binary files,
only what I got were binary files vibrating unstably.
Is any method or function to sooth or blur binary files?
