Optical Character Recognition
A Tutorial for the Course Computational
This tutorial demonstrates how character
recognition can be done with a backpropagation network and shows
how to implement this using the Matlab Neural Network toolbox. This
is a slightly modified version of the character recognition
application of the Matlab Neural Network toolbox (chapter
This tutorial is also available as
The matlab code for this tutorial is part
of the Neural Network Toolbox which is installed at all PCs in the
student PC rooms. To start the tutorial just type appcr1
at the matlab prompt. To get the offline HTML version of this
tutorial and the matlab code as presented in the exercise course
- to download the file nn-ocr.zip.
- Unzip nn-ocr.zip which will generate a
subdirectory named nn-ocr.
- Add the path nn-ocr to the matlab search
path with a command like
if you are using a Windows machine or
if you are using a Unix/Linux machine.
