Oct 03, 2016 · Bubble sheet scanner and test grader using OMR, Python, and OpenCV. In the remainder of this blog post, I’ll discuss what exactly Optical Mark Recognition (OMR) is. I’ll then demonstrate how to implement a bubble sheet test scanner and grader using strictly computer vision and image processing techniques, along with the OpenCV library.
