![]() ![]() One of the down sides of Tesseract is it doesn’t recognize pictures embedded with text. You need to manually do Recognize all on other pages. Take note, however, if you are OCRing a PDF that has multiple pages, Recognize all will only OCR one page at a time. In other words, you don’t need to select any specific text – just hit Recognize all and gImageReader will OCR the whole image/PDF. On images/PDFs that are made up of mostly text you can do a full recognition. Once you have images/PDFs loaded into gImageReader, what to do next depends on what type of images/PDFs they are: …or hit Acquire Image to scan in a document: To start OCR’ing, either hit Open Images and import the images/PDFs you want to OCR… Optically recognizing charactersĪs already mentioned, Tesseract is the engine while gImageReader is the GUI so you don’t have to do anything with Tesseract itself you use Tesseract through gImageReader.Īfter you get past the configuration mumbo jumbo mentioned above, you’ll be met with the following: Unless you specifically changed it, these are found in C:\Program Files\Tesseract-OCR\tessdata (32-bit) and C:\Program Files (x86)\Tesseract-OCR\tessdata (64-bit).Īfter doing all the above mentioned, you are ready to start OCR’ing. Enter the path to Tesseract dictionaries:.If this is the case, just confirm that is it right – no need to change anything (unless its wrong, in which case you do need to change it). Take note that the Tesseract path may be automatically filled in for you. ![]() Unless you specifically changed it, the path for Tesseract is C:\Program Files\Tesseract-OCR for 32-bit machines and C:\Program Files (x86)\Tesseract-OCR for 64-bit machines. Type in the path to your Tesseract installation:.At the Configuration window, you need to do two things: A Configuration dialog will be the first thing you see. Once you have both gImageReader and Tesseract installed, open gImageReader. (Download links are available at the end of this article.) Once you download them both, they both need to be installed. Getting Setupįirst and foremost, you need to download gImageReader and Tesseract OCR they are two separate downloads. GImageReader is a program that serves as a GUI to Tesseract it users Tesseract to process OCR but adds on an interface that the common man can use. The only problem with Tesseract is that for the common user it is a pain in the to use. Since then, Google has been updating and maintaining Tesseract and today Tesseract is once again considered to be one of the most powerful OCR engines available. After 1995 HP stop putting much effort into Tesseract and in 2005 HP released Tesseract’s source code. At its peak, Tesseract was considered one of the best OCR engines out there. Tesseract OCR is an optical character recognition engine that was originally developed and maintained by HP from 1985-1995.

The only problem is, to take advantage of this convenience, one typically has to shell out a lot of cash: Good OCR programs are bloody expensive. Optical character recognition is one of a few types of technology meant to make our lives easier.
