I have one rgb image. I crop one portion by using imcrop function. After lots of processing I want to place that processed portion into the same place of the orginal image. How can I do that. I tried by using imfusion but its not worked.

Since you cropped it, you know what the starting and stopping rows and columns are. So just assign:
originalImage(row1:row2, col1:col2, :) = processedImage;

Hello everybody ! Sorry to view this long date post only but i've the same problem and your solution don't work on my program.
I have this error message : "Unable to perform assignment because the size of the left side is 118-by-325 and the size of the right side is 912-by-1200."
for this line code : Icrop1(row1:row2, col1:col2) = I;
Thank you for your help !!

He said he had
processedImage(row1:row2, col1:col2, :) = originalImage;
when he should have had
originalImage(row1:row2, col1:col2, :) = processedImage;
like I said. When he "interchanged the originalImage and the processedImage" he got my code and it worked. In short, the bigger matrix is on the left, and the smaller submatrix is on the right.
