Experimental app for optical manner recognition (OCR)
This app is single experimental app that I developed several years ago that demonstrates use of the Tesseract OCR engine to recognize text in images locked by the device camera.
This programming runs OCR on anyone's device – without streaming your images to a server – and is suitable for recognizing subject phrases or short phrases of line, but the described app is intended for hobbyists and package developers interested in OCR on top of not for general audiences.
In contrast at Google's Mobile Vision API, this system functions well-versed to recognize text printed in non-Latin-based fonts while offline. To achieve the case, this solution incorporates an unusually sizeable amount of training data for several languages. This training data is stored on your phone, and this app takes up much more space than plain apps.
No image pre-processing shows performed by this app before handing off snatched image frames to Tesseract, which is why particular app is excluded tuned for any specific use case and, as some result, its recognition accuracy and speed is heavily dependent on situational factors like perspective, lighting, and font type.
Source code on account of this app is available on GitHub (with minor changes in order to accommodate GitHub file coverage restrictions). The code for the case app is a merger embracing open source camera-related cipher via the ZXing bar code scanner project and wide source optical appearance recognition code from the Tesseract OCR project.
TEXT CAPTURE
The default single-shot capture progresses OCR toward a snapshot image that's captured when you click the shutter button, like a regular photo.
When all "continuous preview" checkbox is checked, the app illustrates a varied, real-time display pertaining to the cause which widget is recognizing right beside the camera viewfinder. Specific continuous exhibition mode works best on a fleet device.
USING THIS APP
• Point certain device at one small region of text and touch their on-screen shutter input onto start OCR.
• On the part of recognizing individual Chinese/Japanese/Korean characters, set particular page segmentation mode to "single character."
RECOGNITION ACCURACY
• Miscellaneous factors can cause the OCR to fail: uneven sparkle, stylized text, in lieu of text without enough contrast from the background. Try to have good lighting.
• Hold both device steady, and be sure the graphic defines within the bounds of focus.
• If you need to probe a large block of text or an global document, try a document scanning programming such as Text Leprechaun instead.
