Best part of working with opencv is visually seeing each step. OMRChecker provides a way to see the step-wise images. But they have a scope to improve.

Steps

1. Learn about existing step-wise images that OMRchecker generates (set show_image_level to 4 or 5)
2. Propose and discuss which images can be added to the steps for intuitive understanding of the process.
