Finally, save and close Podfile, then in Terminal, within the same directory to which you navigated earlier, type the following: pod install That’s it! As the log output states, “Please close any current Xcode sessions and use ‘LoveInASnap.xcworkspace’ for this project from now on.” Close LoveinASnap.xcodeproj and open OCR_Tutorial_Resources LoveInASnap LoveinASnap.xcworkspace in Xcode. Preparing Xcode for Tesseract Drag tessdata, i.e. Tesseract language data, from the Finder to the Supporting Files group in the Xcode project navigator. Make sure Copy items if needed is checked, the Added Folders option is set to Create folder references, and LoveInASnap is checked before selecting Finish. Note: Make sure tessdata is placed in the Copy Bundle Resources under Build Phases otherwise you’ll receive a cryptic error when running stating the TESSDATA_PREFIX environment variable is not set to the parent directory of your tessdata directory. Back in the project navigator, click the LoveInASnap project file.

Tesseract Mac IMPORTANT This is not an official build of Tesseract. Direct all issues and comments to June 2013 - There is a release up on github (with contributions from others, open source!) July 2011 - There is a new Xcode 4 compatible source download on the November 2010 - Updated for Tesseract 3.0 + minor improvements (This release is based off the older branch, so there isn't a command line tool yet) Sept 2010 - Added universal binary command line tool and an updated XCode project file to build that binary.

If you have an older version of the Mac OS then you'll need to create a Mac Developer ID at the link above and then find the appropriate version of Xcode for your OS: • OSX Mavericks 10.9: Xcode 6.2 • OSX Mountain Lion 10.8: Xcode 5.1.1 • Earlier versions are also available. Be sure to install the full Xcode package ('Xcode 6.2') rather than any of the smaller components like command line tools, etc. You'll need to accept the Xcode license agreement before you can use it or do some of the following steps: • Open your Applications folder and find the new Xcode app • Open Xcode. • Accept the license agreement. • Close Xcode. • Install code and dependancies for Tesseract: • sudo port install autoconf • sudo port install automake • sudo port install libtool • sudo port install jpeg tiff libpng • sudo port install leptonica • Finally, make sure everything is up to date and properly installed: sudo port selfupdate Installing Tesseract: There are a couple of options here at this point.

You can adjust the image a bit for a potentially better OCR experience with convert options like these: convert -sharpen 1 -brightness-contrast 3X30 input.jpg input.tiff.

Feedback of all kind is welcome, especially ideas on how to improve the OCR quality. In the review on this blog the mediocre OCR performance of Tesseract was on of the of this test. How to add more languages One of the key advantages of the Tessearct engine is the wide variety of supported OCR languages - it even includes Esperanto! The (a9t9) Free OCR for Windows Desktop installer includes English (ENG), Spanish (SPA) and German (GER). To add more languages just follow these three steps: • file you need from Google code, for example.

3rd party Windows exe's/installer • Cygwin includes. • binaries compiled by @egorpugin (ref issue # 209) You have to install VC2015 x86 redist from microsoft.com in order to run them. Download a voice changer mac. Leptonica is built with all libs except for libjp2k. • (installers available for version 3 and 4).

With regard to question and question, where I ask how to download thousands of PDF and processes them to extract their texts with OCR, I am hitting a brick wall again when it comes to enhancing the text outputs. I am interested to extract texts of a bunch of PDF in order to search for surnames in the text (I do not need necessarily to be able to read the rest of the text). The PDF represent old newspaper articles, published between 1810 and 1832 and written in. This font seems to be particularly challenging for tesseract. Q: How can I further improve the image quality for tesseract to - at least - have a change to find the surnames in the text? Which procedure would you suggest? If we take pdf as an example, I receive the following image when applying convert -colorspace GRAY -resize 3000x -units PixelsPerInch example.pdf example-page.jpg If I now use tesseract with tesseract --tessdata-dir /usr/local/share/tessdata/ -l deu_frak example-page.jpg example-page.txt it would perform terrible on that image with roughly 360 diacritics detected only.

Are you curious about optical character recognition (OCR) software? Interested in learning how OCR software may be able to enhance your research project? Or, maybe you're interested in the ways in which OCR can aid in textual comparisons.

To use the new project file, you need to download the source package first, then replace the main project file with the updated one from the update archive. January 2009 - Now updated to use the 2.04 release of Tesseract OCR I have produced a universal binary build and a rather simple cocoa front end that allows basic optical character recognition. You paste or drag an image into the lefthand box and converted text appears in the righthand box. This is really only a proof of concept, but if there is interest I might see if it can be developed further.

Chances are you’ll get the best results by combining strategies, so try different approaches and see what works best. As always, if you have comments or questions on this tutorial, Tesseract, or OCR strategies, feel free to join the discussion below!
