平面图形对象拾取算法研究

The Algorithm of Acquiring a Plane Image Object

介绍了在图形处理中,利用面向对象技术实现的平面图形对象拾取算法。与传统的以大量图像信息的存储为基础的位图存储方式下的图形对象拾取算法相比,本算法不但包括单个图形对象的拾取,而且也探讨了在复杂的图形组合下,如在图形重叠与覆盖的情况下进行多个图形对象拾取所需解决的算法难点。本算法对提高图像信息的存储效率和图形对象拾取的质量,对图像科学与面向对象技术的发展具有实际意义。

This paper explains how to acquire a plane picture object in image processing by taking the oriented-object method. Compared with the method of using bitmap, this algorithm improves the memory efficiency and the quality of acquiring an object. It has practically been used in the image science and the onented-object technology.
