Recently, I want to do something about image recognition, so I Google a lot.
And find some open source about image recognition, handwriting recognition and OCR etc.
The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but it is probably one of the most accurate open source OCR engines available. The source code will read a binary, grey or color image and output text. A tiff reader is built in that will read uncompressed TIFF images, or libtiff can be added to read compressed images.
Now it's under Google code. You can get it here
GOCR is an OCR (Optical Character Recognition) program, developed under the GNU Public License. It converts scanned images of text back to text files. Joerg Schulenburg started the program, and now leads a team of developers.
GOCR can be used with different front-ends, which makes it very easy to port to different OSes and architectures. It can open many different image formats, and its quality have been improving in a daily basis.
You can get it from SourceForge.
The Java Object Oriented Neural Network (JOONE) is an open source project that offers a highly adaptable neural network for Java programmers.
The JOONE project source code is covered by a Lesser GNU Public License (LGPL). In a nutshell, this means that the source code is freely available and you need to pay no royalties to use JOONE. JOONE can be downloaded from sourceforge.net.
