Hello there! I'm developing a code in MATLAB that automates the process of calculating the defaulters in a class on a certain parameter(say 75%). My code currently works for computer generated images of attendance sheets but wont work for scanned images as it was intended to.(Both are attached below) Can someone please take a look at the code attached below and guide me in the right direction as I'm freaking out.

Which m-file is the main one? Where does it fail? Are you able to find the boxes inside the grid lines? Or does it do that okay but can't distinguish between a 0 and a 1. Are all your o's guaranteed to be closed? For the 0's and 1's I'd take the convex hull of each and look at the area. If the 0 is rather narrow, then for those "in between areas" you might need to look at other featured, like the Euler number.

Thanks for replying. OCR.m is the main file. Anyway I somehow got it working and it executes perfectly with the values being displayed in the Command line. I now have to create a GUI and reading through the guide documentation, nothing is making sense. Do I have to now segment my code into individual functions for callbacks? what about the sequence of my code? Any advice is welcome. Thanks Clinton
