摘要：

The pictorial contents of a grey-tone picture can be simplified by diminishing the number of regions present in it as well as bg reducing the size of some of them. Lowering operations which do not cause topological changes in the picture can conveniently be used to this purpose. More efficiency can be gained if the pixels to be lowered belong to a class of pixels introduced in this paper as non-ridge points. In fact, non-ridge points are a type of simple points which can be lowered to a grey-value smaller than the one a generic simple point can be decreased, (C) 1999 Pattern Recognition Society.
