Experimental app for optical character recognition (OCR)
Runs the Tesseract OCR engine to find text in images captured by the device camera.
This app runs OCR on your device--without uploading your images to a server--and is suitable for recognizing individual words or short phrases of text.
The default single-shot capture runs OCR on a snapshot image that's captured when you click the shutter button, like a regular photo.
When the "continuous preview" checkbox is checked, the app shows a dynamic, real-time display of what the device is recognizing right beside the camera viewfinder. The continuous preview mode works best on a fast device.
USING THIS APP
• Point the device at a small region of text and touch the on-screen shutter button to start OCR.
• For recognizing individual Chinese/Japanese/Korean characters, set the page segmentation mode to "single character."
• Various factors can cause the OCR to fail: uneven illumination, stylized text, or text without enough contrast from the background. Try to have good lighting.
• Hold the device steady, and be sure the picture is in focus.
• If you need to scan a large block of text or an entire document, try a document scanning app such as Text Fairy instead.
• This app supports several languages/scripts not recognized by Google Translate.
• Supported languages for OCR:
English, Middle (1100-1500)
French, Middle (ca. 1400-1600)
Georgian - Old
Greek, Ancient (-1453)
Greek, Modern (1453-)
Italian - Old
Spanish - Old
