腐蚀可分为一个两步过程,以免分裂目标。请问是哪两个过程?

答案

参考答案:

腐蚀可分为一个两步过程,以免分裂目标。第一步是一个正常的腐蚀,但它是有条件的,也就是说,那些被标为可除去的像素点并不立即消去。在第二步中,只将那些消除后并不破坏连通性的点消除,否则保留。以上每一步都是一个3×3邻域运算,可用查表运算实现。

If you are a parent, grandparent, guardian, or anyone involved in bringing up a child, choosing the right school can be a hard decision. Your choice of school must be made carefully in order to provide the best education for your child.

If you are living overseas and are interested in a school over here, then please visit our International Zone. Similarly, if you are looking for an independent school abroad, you will also find useful information in our International Zone.

There are many things to consider.  Boarding (寄宿) school or day school? Senior, junior, or both? Single-sex or coeducational? Your child may have specific religious needs, a particular talent or a special educational need. How much does an independent education cost? Is help available if I can' t afford the fees? How do I apply for a place?

The ISC information & advice service is a free information service, established by the Independent Schools Council (ISC) to give advice on reliable independent schools in the UK and Ireland. A national information team working for the ISC information & advice service deals with thousands of enquiries (询问). In addition to our easy-to-use online School Search, we offer help, replies to enquiries, and a wealth of information about choosing and applying to an independent school.
