图像处理入门

MATLAB中遇到问题：

>> R= imnoise2('gaussian',100000,1,0,1);

Undefined function 'imnoise2' for input arguments of type 'char'.

>> function R=imnoise(type,M,N,a,b)

function R=imnoise(type,M,N,a,b)

|

Error: Function definitions are not permitted in this context.

解决：打开Matlab程序，左上角File---New----Function； 函数必须写在这里，再在Matlab中调用

>> function R=imnoise(type,M,N,a,b)

function R=imnoise(type,M,N,a,b)

|

Error: Function definitions are not permitted in this context.

>> r = imnoise2('gaussian',100000,1,0,1);

Error: File: imnoise2.m Line: 4 Column: 1

At least one END is missing: the statement may begin here.

图像分割

常用方法：1）用一组种子点来生长区域
2）图像细分为任意且互不相连的区域，再合并或分离这些区域
