用matlab实现对细菌图像进行分割

I1=imread('yabaoganjun1.jpg');
imshow(I1),title('原始图像');
I2=imresize(I1,0.1);
figure(2),imshow(I2),title('放大0.1倍图像');
I3=rgb2gray(I2);
figure(3),imshow(I3),title('灰度图像');
I4=imadjust(I3);%对比度调整法，使图像增强
figure(4),imshow(I4),title('灰度增强图像');
I5=imadjust(I4,[0 1],[1 0]); % 灰度倒置
figure(5),imshow(I5),title('灰度倒置图像');
thresh=graythresh(I5);
bw=im2bw(I5,thresh);
figure(6),imshow(bw),title('二值化图像');
med=medfilt2(bw,[4 4]);
figure(7),imshow(med),title('中值滤波图像');
[labeled,numObjects] = bwlabel(med,4);
numObjects
[r c]=find(labeled==2);% 找第2个物体的位置：行和列
rc=[r c]
