TopOCR Reader 2.0
TopOCR Reader is a PC-based Reading Machine application for use with document cameras that can help someone who has difficulty reading books, magazines or newspapers.
It has a very easy to learn Visually Accessible User Interface and a very powerful state-of-the-art OCR (Optical Character Reading) system that transforms text images into speech that can be played on a headset or saved on an MP3 Player.
TopOCR Reader can read and speak in eleven different languages (English, Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish), and all it takes is just one key F6 to select any of the supported languages.
TopOCR Reader automatically performs text orientation correction on each scanned image, so even if your documents are placed sideways or upside down, TopOCR Reader will always be able to read and display them in the proper orientation. TopOCR Reader will also use its Text To Speech System to notify you if the light level is too low for effective scanning.
TopOCR Reader's Accessible User Interface is completely "self voicing" so it doesn't require an external screen reader. All OCR processing is performed locally on your PC, making the process faster and more convenient. This also makes it possible for you to read documents in situations where you don't have a network connection.
What about OCR accuracy? When TopOCR Reader was compared to KNFB Reader (the leading Accessible OCR Smartphone application), the result of the comparison was that TopOCR Reader with the Tesseract LSTM OCR classifier had 80% less OCR errors thanks to its advanced image processing and OCR technology! Our Sample Camera Images page shows TopOCR Reader is able to read 7 out of 8 of the sample camera images with no errors, and only minor errors on the remaining eighth. If you are using a Windows 10 PC, TopOCR Reader supports the use of TAO OCR which provides even greater OCR performance!
TopOCR Reader also includes the "SeeHear Visual Translator". This function uses a webcam to scan the world and then tells you the different objects that it can recognize!

TAO OCR - Tesseract Accelerated OCR (Windows 10 Only!)
TAO OCR is a very high performance multilingual OCR engine optimized for document cameras.
It can read with greater than 99.8% accuracy with a 5.0 MP document camera, even with lower quality images.
TAO OCR is not only super-accurate, it's also super-fast, with an average reading speed of under two seconds per page!
If you are running on Windows 10, TopOCR Reader will automatically select the TAO OCR recognizer for all supported languages.
If you are running on an earlier version of Windows, TopOCR Reader will instead automatically select the standard Tesseract LSTM recognition engine which is multi-platform.
Note: TAO OCR is a derivitive of the same OCR engine used in Microsoft's "Seeing AI" application! However, instead of an Android or iPhone app, it is available as a Windows DeskTop application with OCR processing that executes directly on your PC instead of through a "cloud" interface. As a result, TopOCR Reader is much faster than any of the current mobile versions of Seeing AI, on top of being more accurate than any previous PC-based Accessible OCR application.
SeeHear Visual Translator
The SeeHear Visual Translator is a Deep Convolutional Neural Network that can recognize 1,000 different types of objects based on the ImageNet Image DataBase.
When you press the SeeHear function key F10, it will announce to you through TopOCR Reader's Text To Speech System a list of 5 objects that it has recognized in a frame captured from your webcam.
SeeHear 27 Layer Deep Neural Network
- arbitrary resolution RGB webcam image is automatically scaled to Neural Network input layer
- 19 deep convolutional layers
- 5 down sampling layers
- 1 non-linear down-sampling layer
- 1 softmax loss layer
- 1 cost layer
- recognition output is automatically converted to Text To Speech and played on your headset
SeeHear's Deep Convolutional Neural Network requires nearly 25 billion floating point calculations to process the full network pipeline with all 27 layers.
It takes about 3 seconds for this network to perform an inference on a VGA sized(640x480) webcam image using a 4-core Intel 3.4GHz i7-6700 (CPU only).
Before you use SeeHear, make sure you have a webcam with a resolution of 640x480 or greater attached to your PC!
To use SeeHear, press the F4 key to select the proper webcam, then point your webcam at any scene you want to recognize, and then press the F10 key. You will immediately hear a "ticking clock" sound that can last from 2-12 seconds depending on the speed of your PC, followed by the list of recognized objects spoken to you through TopOCR Reader's Text To Speech interface. If you want to return to document scanning, then press the F4 key and select your document camera instead of your webcam, or you can press the F10 key again to recognize another frame from your webcam.
A recommended platform to use with SeeHear would be a notebook PC running Windows 10 in the $299 to $599 price range with a built-in webcam and HDMI port.
Note: Currently, SeeHear's list of 1,000 recognizable objects is English only.

TopOCR Reader Configuration
Once you've installed TopOCR Reader on your PC then you're ready to configure it for use with your document camera.
This generally only needs to be done once and takes just a few seconds to complete.
1. Plug your document camera into a USB 2.0 port on your PC.
2. Launch the TopOCR Reader application by typing Ctrl+Alt+Q from the DeskTop Window.
3. TopOCR Reader's default language is English, if you want to use the Accessibile User Interface with another language, then use the F6 key to select another language.
4. If you have a PC with more than one webcam/document camera, use the F4 key to select the correct document camera.
TopOCR Reader's configuration, like its operation is 100% Accessible, there are no on screen dialogs, menus, or buttons that would require the use of an external screen reader. All functions are handled through the keyboard.
Please note that if you're using Windows 7 then you'll also need to download and install the Text To Speech Engine and required Voices. If you're using Windows 8 or Windows 10 on non-US English versions of Windows you will also need to download the appropriate voices as they may not be included on your platform.
TopOCR Reader and the Clipboard
After OCR, TopOCR Reader automatically places the recognized text in the clipboard, and it also allows you to paste images with "Control-V" into the clipboard and have them automatically read to you.
A "quick and dirty" screen reader can be easily implemented in TopOCR Reader by typing "Ctrl + Alt + Print Screen" and then typing "Control V" in TopOCR Reader.
TopOCR Reader's Global Illumination Check
Whenever you press the F1 key to OCR a document, TopOCR Reader will measure the total amount of available light on the scanned image.
If this value is too low then TopOCR Reader will give you a text to speech warning and will also provide you with the global illumination value.
If this number is very low, below 10 for instance, it means that there is very little illumination.
Please note that if you have a dark background and a small text image, it can give a lower than expected value, and as a result may generate a false warning.
