Optical mark recognition (OMR) collects data from people by identifying markings on a paper. OMR enables the hourly processing of hundreds or even thousands of documents. A common application of this technology is used in exams, where students mark cells as their answers. This allows for very fast automated grading of exam sheets.

In the OMR technology is fundamental the way in which it is discriminated a box blackened to a box empty. Working on a digital image, usually binarized, the usual discriminant used to evaluate if a box is full or empty, is represented by the ratio between black pixel and white puxel in the area covered by the box: selecting an appropriate ...

Jul 12, 2023 · This scenario airs the need for a flexible OMR system. Hence, in this work, we propose a lightweight transfer learning based Convolutional Neural Network (CNN) model, dubbed as OMRNet, which can classify answer boxes on any generalized OMR test sheet.

What is a checkmark and how can it be recognized? A checkmark field is an element on a form - it is usually of a rectangular shape and therefore often called a “check box”. In this element, the user of a form should make 'a sign' to indicate his opinion, decision, or selection - a check/tick, an X, a large dot, inking over, or others.
