The overall research work contains a number of procedural steps. Such as
converting a black and white image to grayscale and various image
processing steps, learning a pattern using Back-propagation Neural
Network (BPN) and Bidirectional Associative Memory (BAM) recognize a
existing or non-existing pattern from the learned pattern using BAM and
BPN technique. All the steps of image processing and feature detection
steps are performed and coded by the programming language Matlab
provided by the Matwork Inc. Primary operation of Matlab is to acquire
an image from the storage disk which is stored in a specific format and
process the image. One of the most important factors of the research
work is Feature Extraction which is implemented by Matlab. Then the
processed pattern is stored in a file such that the file can be
processed by another procedure. In pattern learning BPN and BAM is used.
The parameters of the learning algorithm are varied and observed the
nature of the system. From pattern learning, we get a weight set and
correlation matrix which is used in recognition.
