How to solve error "Error using bwmorph"
显示 更早的评论
I want to doing a feature extraction steps for multiple images, i have this function:
% this function is supposed to extract features from the input image
function [features]=feature_extraction(I)
if length(size(I))>2 % checking if rgb image;
I=im2bw(I,graythresh(I));
end
I=bwmorph(I,'skel',inf);
I=discourser(I);
row=size(I,1);
column=size(I,2); ... and so on.
And I call it in another script.
files = dir('*.png');
for i = 1:numel(files)
I = files(i).name;
[getfeature] = feature_extraction(I);
end

You omitted the error message.

Yes, to be expected when you pass in the name of the file instead of the content of the file.

I understand that. What I'm saying is that if you put the responses into into a file and then run
myexe.exe < c:\temp\inputs.txt
in the command shell and then, assuming that works,
system('myexe.exe < c:\temp\inputs.txt')
does it work?

You are passing the file name into the function. The name of the file does not have more than 2 dimensions so you do not use im2bw(). You are passing the name of the file to bwmorph. bwmorph is not defined for character strings.
Have you considered the possibility of reading the file content at some point?
