2023:Zonal OMR (Value Extractor): Difference between revisions

Revision as of 10:02, 19 December 2023

The Zonal OMR extractor is mostly an outdated tool and should only be used if all other OMR extractor options have been exhausted. It requires the most manual setup of any OMR extractor to configure.

About

In previous versions of Grooper (prior to Grooper 2021), OMR extraction was quite different and took a bit more setup than the OMR extractors we can use in Grooper 2023. Now called Zonal OMR, this previous method of OMR extraction still exists, for the most part, for upgrading repositories from old versions of Grooper. That way, anything that used this outdated version of OMR extraction still works in new versions.

It is recommended that you use Labeled OMR or Ordered OMR instead, but as a last resort, you can fall back on Zonal OMR.

⚠	Zonal OMR can only be used with OMR boxes. It will not detect radio buttons. If your document has radio buttons you want returned, you will have to use Labeled OMR for that.

How To

For Zonal OMR to work, we have to assign a Value to each OMR Box individually and tell Grooper where to look for the box on the document.

In the example below, we are using a simple document indicating different emotions. We are going to assign a different emotion to each OMR box and Grooper will return the value assigned to the checked box.

You can use Zonal OMR in more complex situations. In the example below, we show a diagram that is being used to indicate the area of impact to a vehicle from a car accident. We can use Zonal OMR to return this type of information.
