In order to judge the grade of pimento, some parameters are extracted from two-dimensional image of pimento. These extracted parameters consist of length, width, perimeter, projected area, projected area to squared perimeter ratio, and width to length ratio. The extracted parameters and grade of pimento judged by experienced workers are used as input and desired patterns to estimate the connection weights of neural network. In this paper, a three-layer feed-forward neural network and back-propagation learning algorithm are suggested for the shape and size grading of pimento.
