Hi,
I would like to determine the surface rougness of a microscopic picture.
I have code that creates a depth map:
File_Name='CPTi_D2_75_right_off_centre.tif';
% micron/pixel
% this is the spatial resolution of the input
Resolution=0.459;
% Number of intensity levels in the image,
% if you think that the result porosity is overestimated,
% just increase this number and vice versa, it accepts integers
N=18;
A = imread(File_Name);
if ndims(A) == 3
B = rgb2gray(A);
end
level = multithresh(B ,N);
C= imquantize(B,level);
RGB1 = label2rgb(B);
imwrite(RGB1,[File_Name(1:end-4) '_Depth Map.png']);
P=zeros(size(C));
for I=1:size(C,1)
for J=1:size(C,2)
if C(I,J)==1
P(I,J)=1;
end
end
end
P=1-P;
P=bwmorph(P,'majority',1);
figure;
imshow(RGB1); title('Depth Map')
I would like to use to create a 2D graph of the various distances and then use that to calculate the surface roughness.
Can anyone help me with this? Would it be possible? If not, any other suggestions?
Thank you for taking the time to assist me.
Kind Regards,
Andri
