| 摘 要： | 以大豆叶片为例,介绍了一种提取叶片有效点计算叶片特征参数的新方法.该方法用Matlab编程来识别象素点颜色,进而求出叶片特征区域包含的象素点数及对应的特征值.通过理论分析及对比可以证明,利用象素点计数的方法来求特征值不仅简单,而且也是对原始模拟区域的无偏和一致的最好估计.

| Abstract: | Set laminae of soya for example, this paper introduces a new method of calculating feature parameter based on extracting effective points,which can get the pixels and its feature parameter.The experiment proves that using this method is not only easy to calculate feature parameter, but also the best estimate for non-warp and consistence of the primordial simulation through theoretical analysis and contrast. |
