Hello everyone, I am trying to save my images using imwrite() but its hitting "Index exceeds matrix dimensions." error at line no 134 i.e at " imwrite(final_img, strcat(output_folder, srcFiles(i).name));" I am not getting how to resolve this error. If any of you have an answer to this please tell me. Thank you!!

I just had a quick look but it seems to me that you're using "i" as an index in different (and nested) loops, so the values in nested loops override your the value of i in the main loop.
