图像处理时,需要将所有图像转化为灰度图,采用下面的代码
if(isgray(a)==false)
a=rgb2gray(a);
end;
结果出现警告:Warning: isrgb is obsolete and may be removed in the future
网上搜索了n久,木有找到解决方法。
偶然想到在C++里边用try来处理一些不确定的东东,于是尝试搜索matlab是否有try语句,没想到还真有!于是将上面的代码做如下改动:
try
a=rgb2gray(a);
catch
;
end
一切ok!
另一种方法
if size(a,3)==3
a=rgb2gray(a);
end
