Hello,
When I run the following code I get this message: ??? [BW,threshold]=edge(img,’zerocross’,[],'Laplacian'); | Error: The input character is not valid in MATLAB statements or expressions.
Could someone help me?
Thanks in advance
%%%%%% code%%%%%% clc;close all;clear *;
Laplacian=[1 1 1; 1 -8 1; 1 1 1];
img=double(imread('C:\Users\manolis\Desktop\ask4 sagkriwths\clown.tif')); [BW,threshold]=edge(img,’zerocross’,[],'Laplacian'); figure;imshow(img,[]) figure;imshow(BW)
disp(threshold)

That's better, but I meant replace your code in the question by the formatted code (click on "Edit").

You have the wrong kind of quotes around zerocross and should not have quotes around Laplacian. Try this:
[BW,threshold]=edge(img,'zerocross',[],Laplacian);
