Purpose
Image filtering
Synopsis
- xf = spatial_filter(x,win,options)
Description
Inputs
- x = image data class 'double' or 'dataset'. If 'dataset' it must x.type=='image'. If 'double' it must be MxNxP (P can = 1).
- win = a 1 or 2 element vector of odd integers corresponding to the window width of the box filter. If scalar, (win) is set to win = [win win].
Outputs
- xf = Filtered image class 'dataset'.
Options
options = a structure array with the following fields:
- algorithm: [ {'gaussian'} | 'box'] Point source function for filtering.
- 'gaussian' - (win) corresponds to the std in the Gaussian distribution.
- 'box' - (win) is the number of x- and y- channels.
