Tesseract OCR and the HoverCam
Tesseract OCR comes free with HoverCam Flex software suite. You may have noticed in the Archive tab of HoverCam Flex that there is a tab labelled “OCR.” “OCR” is an abbreviation for “optical character recognition.” In other words, it digitizes printed pages. You can take a print out or book, scan it, and have text that you could edit in your favorite word processing program.
Tesseract OCR, included in HoverCam Flex, is the same OCR engine currently used by Google. Tesseract OCR was named one of the top OCR engines in the 1995. It is considered one of the most accurate open source OCR engines available. Combined with a HoverCam document camera, it can read a wide variety of image formats and convert them to text. From that point, the digitized document can be read back to the user with Text-To-Speech.
How to use Tesseract OCR
In HoverCam Flex, you can get the best results from Tesseract OCR by scanning dark uniform letters on a white background with a font size of 10 or greater. Be certain to crop your image to just the text and try to avoid pictures or symbols. Once digitized, click on the audio symbol at the bottom of the screen to activate your computer’s Text-To-Speech.
