评论： Iliana about 2 hours 前

Hello all,

I would like to implement a gaussian filter on my A-scan (1D) from an OCT image (B-scan, 2D). The A-scan essentially represents how the intensity values fluctuate versus the depth.

I would appreciate your help.

Thank you :)

在 MATLAB Online 中打开

See imgaussfilt, e.g.,

A=zeros(1,11); A((end+1)/2)=1
A = 1x11
     0     0     0     0     0     1     0     0     0     0     0

B=imgaussfilt(A,1.2)
B = 1x11
         0         0    0.0146    0.0831    0.2356    0.3333    0.2356    0.0831    0.0146         0         0
