1D median filtering

how to apply 1D median filter with 100ms window length?

Answer 1

[David Young]

Assuming your data are stored as a row vector D, and the sampling interval is T ms, and you have the Image Processing Toolbox, you could do this:

windowlength = 100;
windowsize = ceil(windowlength/T);
D_filtered = medfilt2(D, [1 windowsize]);

If the data are stored as a column vector, use

D_filtered = medfilt2(D, [windowsize 1]);

instead of the final line.

I have 2 cols and 6000 rows in a mat file. How can I apply relaxed median filter? Im not able to understand how to set window and lower and upper bounds for mat file which is 2 cols and 6000rows.
