Matlab watershed函数学习(1)



function L =watershed(varargin)

%WATERSHED Watershedtransform.

%   L = WATERSHED(A) computes a label matrixidentifying the watershed

%   regions of the input matrix A.  A can have any dimension.  The elements

%   of L are integer values greater than orequal to 0.  The elements

%   labeled 0 do not belong to a uniquewatershed region.  These are called

%   "watershed pixels."  The elements labeled 1 belong to the first

%   watershed region, the elements labeled 2belong to the second watershed

%   region, and so on.

 

L =WATERSHED(A) 计算一个标签矩阵, 用于识别输入矩阵A的汇水区域. A可以是任意维. L的元素均为大于等于0的整数值. 标签值为0的元素不属于任何一个汇水区域, 称它们为"分水岭". 标签值为1的元素属于第1个汇水区域, 标签值为2的元素属于第2个汇水区域, 以此类推.

 

%   By default, WATERSHED uses 8-connectedneighborhoods for 2-D inputs

%   and 26-connected neighborhoods for 3-Dinputs.  For higher

%   dimensions, WATERSHED uses the connectivitygiven by

%   CONNDEF(NDIMS(A),'maximal').

WATERSHED默认对2维输入数据采用8邻接, 对3维输入数据采用26邻接. 对于更高维数的输入, WATERSHED根据CONNDEF
