Character Recognition

Character Recognition is an Android app that allows the user to take a photo (or use existing image files on the device) and then apply the Tesseract OCR engine to extract the text in the photo. It is currently supporting English text, but other language support will be added in the future.

      Release Notes: Improves the image display (which may also also recognition results overlay if available) to allow zooming in and out using multi touch. Removes the English training data from being bundled with the package to reduce initial package download size. This means the initial English training data are also downloaded separately after the program is first run.

        Release Notes: Changes were made in the Tesseract engine settings for more accurate results and better handling of text at various directions. Overlaying drawings of the detected text on the image at the detected location was added, beginning a move towards a more Argument Reality-style display.

          Release Notes: This release adds a bugfix for training data downloads, which seemed to take longer than normal. The download progress dialog also now shows the percentage completed.

          •  28 May 2013 19:03

            Release Notes: This release adds support for most languages supported in Tesseract-OCR by downloading the training data from the Google code Teseract-OCR release site. Only English training data comes with the app download, but if the user now chooses another language, the app will download the language's training data. Once the data are installed, the app will be able to do recognition in that language in future runs. Thus, this release significantly increases the usefulness of the app.
