I. Introduction
Almost as soon as digital computers became available, it was realized that they could be used to
process and extract information from digitalized images. Need of accurate grading, sorting of fruits and foods,
or agriculture products arises because of increased expectations in quality food and safety standards. This is
being assessed through visual inspection by human inspectors. This process is tedious and time consuming.
After hours of working the operator may loose concentration which in turn will affect the evaluation process.
The farmers are very much affected by this manual activity in terms of returns for their crop. Hence these tasks
require automation, so as to have a computer vision system as an alternative to this manual practice. Automated
system of sorting food and agriculture products provides rapid and hygienic inspection with computer vision.
Computer vision and image processing are non destructive, accurate and reliable methods to achieve
target of grading. Machine Vision Systems are successfully used for Identification and Classification of plants,
leaves, flowers, bulk grain samples. In order to perform this task of pattern recognition by machines,
considerable design effort is necessary. Characterization models were based on morphological features, color
features or textural features. After isolating the grain, the region of interest was selected around the boundary of
the edge. The morphological features were obtained from the binary images containing only pixels of the grain
edge.
