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.

Certain types of applications require reading text from documents that are stored as graphical images. That is the case of scanned documents. An OCR (Optical Character Recognition) tool can be used to recover the original text that is written in scanned documents. These are sophisticated tools that are trained to recognize text in graphical images. This class provides a base implementation for an OCR tool. It can be trained to learn how to recognize each letter drawn in an image. Then it can be used to recognize longer texts in real documents. Manuel Lemos |
