See also: wanghaisheng/awesome-ocr - A curated list of promising OCR resources at GitHub. Tessnet2 is under Apache 2 license (like tesseract), meaning you can use it like you want, included in commercial products.įew others: ABBYY CLI OCR for Linux, Asprise OCRįor more complete list, check: List of optical character recognition software at Wikipedia That expose very simple methods to do OCR. Tesseract is a C++ open source OCR engine. We expect that it will also be an excellent OCR system for many other Intended for high-throughput, high-volume document conversion efforts. OCRopus is development is sponsored by Google and is initially High-performance handwriting recognizer developed in the mid-90's andĭeployed by the US Census bureau, and novel high-performance layout The OCRopus engine is based on two research projects: a Large scale machine learning for addressing problems in documentĪnalysis, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, and multi-lingual capabilities. OCRopus™ ( FAQ) (written in Python, NumPy, and SciPy) Open many different image formats, and its quality have been improving Makes it very easy to port to different OSes and architectures. GOCR can be used with different front-ends, which It converts scanned images of textīack to text files. Tesseract is probably the most accurate open source NET, Tesseract iOSĪn OCR Engine that was developed at HP Labs between 19.Īnd now at Google. There are few popular OCR command-line tools you can use (I'm not sure if they've GUI):Īlso available for: Tesseract. Tesseract can only read a TIFF file - if you've got a JPEG or PDF or whatever, you'll have to convert it. To run tesseract goto terminal and type the following tesseract imagefile.tif outputfile.txt Is Command line utility and it is very simple to use.You can install language package tesseract-ocr-eng from here. Is a document layout analysis and optical character recognition system. Is a KDE application but works fine,in addition you have to install actual OCR programs like GOCR and OCRAD.After installing Kooka and the OCR programs,you have to point Kooka to the OCR install location in order for it to be able to convert the JPEG to text. Is an OCR can be used as a stand-alone console application,or as a backend to other programs. About Swift Swift is a new programming language for iOS and OS X apps that builds on the best. 1.Is an OCR (Optical Character Recognition) program.It converts scanned images of text back to text files. SwiftScan packs all the power of a desktop scanner into. These models only work with the Tesseract. 2.x tessdata_v3 - Version of trained models for tesseract 3.04 or 3.05. The legacy tesseract models have been removed for Indic and Arabic script language files. So, they should be faster but probably a little less accurate than tessdata_best. The LSTM models in these files have been updated to the integerized versions of tessdata_best. 2.x tessdata_main - Version of trained models for legacy tesseract engine as well as the new LSTM neural net based engine. These models only work with the LSTM OCR engine of Tesseract.Net SDK ver. The legacy tesseract engine is not supported with these files, so Tesseract's oem modes '0' and '2' won't work with them. When using the models in this repository, only the new LSTM-based OCR engine is supported.The "best value for money" network configuration was then integerized for further speed.For some languages, this is still best, but for most not.These are a speed/accuracy compromise as to what offered the best "value for money" in speed vs accuracy.Provides an alternate set of integerized LSTM models which have been built with a smaller network. Net SDK.īest “value for money” in speed vs accuracy, Integer models. Disclaimer: This webpage is intended to provide you information about patch announcement for certain specific software products. 2.x tessdata_fast – Fast integer versions of trained models for the Tesseract. These models only work with the LSTM OCR engine of Tesseract. Tessdata_best is for people willing to trade a lot of speed for slightly better accuracy. These are the only models that can be used as base for finetune training. Net SDK.īest results on Google’s eval data, slower, Float models. tesseract.dll 32-bit version of the tesseract library for WindowsĪll language files are downloaded from the official repository Tesseract Open Source OCR Engine tessdata_best – Best (most accurate) trained models for the Tesseract.tesseract.dll 64-bit version of the tesseract library for Windows.pdf.ttf Custom font used on PDF generation.equ.traineddata Math / equation detection module (tessdata_main).osd.traineddata Orientation and Script Detection Data (tessdata_main).eng.traineddata English language data (tessdata_main).All of the above packages include the following:
