PHP OCR Class: Recognize text & objects in graphical images

This is class can be used as a tool for optical character recognition.

It can recognize text in monochrome graphical images after a training phase. The training phase is necessary to let the class build recognition data structures from images that have known characters.

The training data structures are used during the recognition process to attempt to identify text in real images using the corner algorithm.
This recommendation solves the problem.
This recommendation does not solve the problem.

This is not a trivial problem but there is a package for that.

It can train the recognition engine with images of existing letters. Once the training is done it can start recognizing text in the pictures.

It is not limited to the letters provided for training. So you can improve the recognition capabilities adding more pictures of other letters you want it to recognize.

It just seems to not be able to take TIFF images as input format, but you can convert the TIFF images to PNG format.
