[Applications] nsdcalc DL : 0: INSTRUCTIONS FOR RUNNING NSDCALC SOFTWARE Nsdcalc.m is a Matlab program for performing the image enhancement process described in the accompanying paper. Place the program in your work directory along with the demonstration data file grav.txt. At the Matlab prompt type >> g=load( grav.txt ) -and you should see a variable called g which is 200x200 double precision reals appear in the workspace. To filter this data type >> f=nsdcalc(g,3,0) which will calculate the standard deviation in a 3x3 window and apply no prior smoothing. The results will then appear onscreen in a window. You may need to adjust the histogram of the output for optimal display.-Nsdcalc is a Matlab program that performs normalised standard deviation analysis for edge enhancement of gravity and EM potential-field datasets
