MATLAB基本图像处理——简单的操作

只记录一部分，存存图

clear,close all
I=imread('rice.png');
imshow(I);
background=imopen(I,strel('disk',15));
%imshow(background)
%figure,surf(double(background(1:8:end,1:8:end))),zlim([0 256]);
%set(gca,'Ydir','reverse');

I2=imsubtract(I,background);
figure,imshow(I2)

I3=imadjust(I2,stretchlim(I2),[0 1]);
figure,imshow(I3)
