Hi all, I have set images 3D (256x256x90 uint16), let say P. Anyone know how to know the smallest number after 0?
>> min(min(min(P)))
ans =
uint16
0
>> max(max(max(P)))
ans =
uint16
1387

After 0 is 1, since we are talking about the integer type uint16.

If you want to find the smallest number greater than 0 that is in your image data, you can do this:
min(P(P > 0))

Ran in:
P = randi([0 65535], [5 5 10], 'uint16'); % smaller size for demonstration
P1 = P(:);
min(P1(P1>0))
ans = uint16 141
