探讨了矩形件和任意形状图案的排样优化问题的遗传算法求解,提出了剩余矩形表示法和条形图表示法。对于矩形排样，剩余矩形表示法提高了板材利用率，更容易得到较优解。对于任意形状图案排样，条形图表示法直接利用位图排样，不对图案作任何限制（允许有孔洞），排样速度很快。该算法已应用于智能印花分色系统中。-on rectangular pieces of arbitrary shape and pattern layout of genetic optimization algorithm. the remai

图像的形状特征一般是在物体从图像中分割出来以后进行分析，形状特征描述与尺寸测量结合起来可以作为区分不同物体的依据。形状特征有两类表示方法，一类是边界特征，另一类是区域特征。图像的轮廓特征主要针对物体的外边界，而图像的区域特征则关系到整个形状区域。(The shape feature of an image is generally analyzed after the object is segmented from the image. The combination of shape fea
