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.

本文以青椒为对象，首先利用数位影像处理技术从人工分级后的各等级产品的影像中萃取出周长、投影面积、长度、宽度、投影面积对周长平方比与宽度对长度比等可作为判断青椒等级的分级准则，再利用多层前馈式类神经网路来模拟农产品的分级作业，并采用反向传递演算法学习各项分级准则与等级判断结果间的关系，以量化了解各项分级准则对等级判断结果的影响程度。
