OCR module in Oxygen Forensic® Detective

What is OCR?

Optical Character Recognition (OCR) automatically identifies typed, handwritten, or printed text located within an image and converts it into machine-encoded text. Whether it’s from a scanned document, a photo of a document, a screenshot of a conversation, or an image with subtitles, we can convert it. The OCR module is now built-into Oxygen Forensic® Detective and available at no additional charge, starting with version 13.0 of the software.

Benefits of OCR

Using the built-in, automated OCR module, investigators can easily conduct searches for words located in images.  This is done by converting images containing text to allow for recognizable searchable characters. This feature is an incredible time-saver, as investigators no longer need to manually search image data for possible evidentiary material. The OCR tool becomes even more useful when dealing with large backups, taking little time to recognize and convert all text from images and screenshots on the device.

Additionally, we have given our users control over their OCR settings. Investigators can change the minimum image size, adjust the import settings, or add supported languages.
