Commercial and OpenSource OCR Softwares

Royalty-free OCR SDK for developers to use in custom applications

Open Source Journal

After testing the FineReader, OmniPage, ReadIRIS, and SimpleOCR, Aspire, Tesseract….it is evident that ABBYY FineReader 9 is the best overall value, while ReadIRIS is the best OCR software for under $150.

The main features that differentiate OCR software are:

  • Character recognition accuracy
  • Page layout reconstruction accuracy
  • Support for languages
  • Support for searchable PDF output
  • Speed
  • User interface
  • API / SDK
  • Support / Consulting
  • Stability of the engine when processing large documents

Following are some of the Softwares that I played with and compared.

SimpleOCR is the popular freeware OCR software with hundreds of thousands of users worldwide.  SimpleOCR is also a royalty-free OCR SDK for developers to use in their custom applications. If you have a scanner and want to avoid retyping your documents, SimpleOCR is the fast, free way to do it.  The SimpleOCR freeware is 100% free and not limited in any way.  Anyone can use SimpleOCR for free–home users, educational institutions, even corporate users. Our own freeware OCR application provides acceptable accuracy for those who just need to convert a few pages and can’t justify the cost of commercial OCR software.  Developers can use the command-line and SDK versions to integrate SimpleOCR with their custom applications.

ABBYY FineReader
FineReader Professional is a highly accurate and easy to use OCR software that includes host of features including digital camera OCR, intelligent document layouts, image enhancement, barcode recognition and command line integration.  FineReader 9 is our pick for OCR software because its document layout retention will save you much time in reformatting documents you convert for editing

IRIS ReadIRIS
Affordable OCR software for business and home users.  ReadIRIS Pro provides a extremely accurate OCR recognition rate at a low cost, but still has some of the advanced features that higher priced professional OCR software includes.

Nuance OmniPage
OmniPage is widely considered the fastest, most accurate and fully featured OCR software.  OmniPage 17 Professional has a unique new feature that lets you convert any type of document to searchable PDF or Word. OmniPage does not have a downloadable demo. Nuance also does not provide free technical support after the first call.  For these reasons we recommend the ABBYY and IRIS products instead.

OmniPage is an Optical character recognition application available from Nuance Communications. Nuance Communications was acquired by ScanSoft, which also took over its name in October 2005.OmniPage converts images such as scanned paper documents, and PDF files, into file formats used by computer applications such as Microsoft Word, Excel, Adobe Acrobat, or HTML files.OmniPage is in competition with ExperVision (TypeReader), Readiris and ABBYY Fine Reader as well as free software such as GOCR and Tesseract.

http://code.google.com/p/tesseract-ocr
In computer software, Tesseract is a free optical character recognition engine. It was originally developed as proprietary software at Hewlett-Packard between 1985 until 1995. After ten years without any development taking place, Hewlett Packard and UNLV released it as open source in 2005. Tesseract is currently developed by Google and released under the Apache License, Version 2.0.

http://jmagick.wiki.sourceforge.net
JMagick is an open source Java interface of ImageMagick. It is implemented in the form of Java Native Interface (JNI) into the ImageMagick API. JMagick does not attempt to make the ImageMagick API object-oriented. It is merely a thin interface layer into the ImageMagick API. JMagick currently only implements a subset of ImageMagick APIs. Should you require unimplemented features in JMagick, please join the mailing list and make a request. JMagick has a LGPL (Lesser GNU Public License) license.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository.

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world.

Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
