I implemented the following code for non-overlapping patch and I'm getting this error. What does this mean?
Thank you.
*Code -*
YourImage = im2double('house.jpg');
[m,n] = size(YourImage);
Blocks = cell(m/16,n/16);
counti = 0;
for i = 1:16:m-15
counti = counti + 1;
countj = 0;
for j = 1:16:n-15
countj = countj + 1;
Blocks{counti,countj} = YourImage(i:i+15,j:j+15);
end
end
*Error Message -*

"What does this mean?"
The IM2DOUBLE documentation states that its first input must be an "Input image, specified as a numeric scalar, vector, matrix, or multidimensional array." Instead of providing a numeric image, you have called IM2DOUBLE with some text.
I do not see anything in the IM2DOUBLE documentation to suggest that it accepts text as its first input.
If you are trying to import an image from a file try using an image importing function, e.g. IMREAD:

Your code does not use im2double. And you did not post the entire error message (all the red text). I know because the line number and actual line of code is not included in what you post, and they are in the actual error message. We can't see what you really did So...
