biimageshow.m

可以直接用

function ResultImage=BiImageShow(Image,T,WhiteBlack)
%Image:输入数据
%T：阈值
%WhiteBlack:决定黑白色,1:大于等于阈值为白；0:相反

Image=double(Image);
T=double(T);
[m,n]=size(Image);
ResultImage=zeros(m,n);
for i=1:m%行
    for j=1:n%列
       if WhiteBlack==1
         
           if Image(i,j)>=T;%大于等于阈值为白
              ResultImage(i,j)=255;
           else
              ResultImage(i,j)=0;
           end

       else
        
           if Image(i,j)<=T;%小于等于阈值为白
              ResultImage(i,j)=255;
           else
              ResultImage(i,j)=0;
           end
           
       end
    end
end

ResultImage=uint8(ResultImage);
% figure,imshow(ResultImage);
% ResultImage=Image;
