Web based, Open Source alternative to Remark OMR or Teleform
queXF, a CADE (Computer Assisted Data Entry) Tool, processes filled paper forms that were created in queXML, such as survey questionnaires. queXF can be used as a web based, Open Source alternative to programs such as Cardiff Teleform and Remark OMR.
Optical Mark recognition with MySQL database and PHP scripts
http://omr-ai.sourceforge.net/ described how to use MySQL and PHP for OMR. The PHP scripts were very much dependent on scanned page size and resolution.
I have written the OMR page format and PHP scripts which are more flexible in nature. This script used horizontal and vertical guides to identify area to be analysed for MCQ answer checking and also identify and correct tilt.
OMR-AI is a very flexible and customizable optical mark reader through which even plain paper can be used as OMR sheet. PHP and MySQL constitutes the core of OMR-AI. Calculating marks, storing result and automating are the main feature.
