OCR and Versions from Google Docs

OCR textGoogle Docs continues to add new features. Two that have caught my attention are:

  • Optical Character Recognition (OCR)
  • Revision History

Optical Character Recognition (OCR) lets you convert images with text into text documents using automated computer algorithms. Images can be processed individually (.jpg, .png, and .gif files) or in multi-page PDF documents (.pdf). These are some of the types of files suitable for OCR:

  • Image or PDF files obtained using flatbed scanners
  • Photos taken with digital cameras or mobile phones

Revision History lets you see all the dates and who made changes to a document, spreadsheet, etc. Once you log into Google Docs, open any document, spreadsheet or other Google doc, you can see all the revisions of your work by using File>see Revision history. The revision system in Google Docs is not a real revision system (such as those in DM software), but rather a continue undo-stack — i.e. your changes are recorded and stacked onto other changes. Google Docs ‘revision history’ allows you to compare earlier states of the document (as recorded on this stack of changes). It also allows you to change the document state to an earlier state without losing any changes.

More new features, and there are many, are listed at : http://www.google.com/google-d-s/whatsnew.html. Which features do you use?
