摘要: 提出了二值化图象离散线性变换的一种新方法.该方法根据象素点的邻域特征保证 变换后图象的连接性,消除虚假的孔洞.它适用于任意形式的线性变换,并不局限于平移、比 例、旋转等特殊情况.实验结果表明,该方法可以消除变换后图象的孔洞,使结果更加真实、有 效.Abstract: A new method for discrete linear transformations of binary images is presented which is based upon the neighborhood features of pixels. This method can perform the transformation while eliminating superfluous holes and keeping the connectivity of the transformed images. It can handle all kinds of linear transformation and is not limited to the special cases of translation, scaling and rotation. Hence, the transformation results become more consistent and accurate. Experimental results show the efficiency of the mehtod.
