Accepted Answer: Image Analyst
Open in MATLAB Online
ipDir = '../Dataset/photos'; isDir = '../Dataset/sketches';
files_p = dir([ipDir '*.jpg']); files_s = dir([isDir '*.jpg']);
tmp1=imread([ipDir files_p(1).name]); Index exceeds matrix dimensions.
Error in createTrainingData_color (line 13) tmp1=imread([ipDir files_p(1).name]);
I am getting the above error. Please help me.
I am getting the error while reading the images.

Evidently the length is zero and so when you try to access index 1, it says "Index exceeds matrix dimensions." Try this more robust way:
if length(files_p) > 0
fullFileName = fullfile(ipDir, files_p(1).name);
tmp1=imread(fullFileName);
end

%IRs
for m=1:nRowPatch
for n=1:nColPatch
squareSum(m,n,i)=intImg(m,n,i)+intImg(m+pSize(1)-1,n+pSize(2)-1,i)-intImg(m,n+pSize(2)-1,i)-intImg(m+pSize(1)-1,n,i);
end
end
tmp2=imread([isDir files_s(i).name]);
sImg(:,:,i)=single(tmp2);
end
this is the code if i mention yours code i got another error pl check he code if possible

Now you've totally confused us. You've accepted the answer but then you've posted chunks of code in three different locations and say it's not solved. Please clarify. Edit or delete your other posts so you just have one response to me in one place.
