I want to read 2 images, do something to those images and then save those two images in a folder. I have used for loop. I am able to read both the images but only first image is getting saved in the folder. Following is my code. What changes should be done in order to save both the images in a folder.
c=cell(1,2);
for m=1:2
I=imread(sprintf('isha%d.jpg',m));
%To detect Mouth
MouthDetect = vision.CascadeObjectDetector('Mouth','MergeThreshold',120);
BB=step(MouthDetect,I);
figure,
imshow(I); hold on
for i = 1:size(BB,1)
rectangle('Position',BB(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','r');
end
x=imcrop(I,BB);
y= imcomplement(x);
figure, imshow(y);
imwrite(y,strcat('D:\implementation\featurescrop\mouth__',num2str(i),'.jpg'));
hold off;
%To detect Eyes
EyeDetect = vision.CascadeObjectDetector('EyePairBig');
BB=step(EyeDetect,I);
hold on
rectangle('Position',BB,'LineWidth',4,'LineStyle','-','EdgeColor','b')
x=imcrop(I,BB);
y= imcomplement(x);
figure, imshow(y);
imwrite(y,strcat('D:\implementation\featurescrop\eyes__',num2str(i),'.jpg'));
hold off;
%to detect nose
NoseDetect = vision.CascadeObjectDetector('Nose','MergeThreshold',85);
BB=step(NoseDetect,I);
figure,
imshow(I); hold on
for i = 1:size(BB,1)
rectangle('Position',BB(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','b');
end
title('Nose Detection');
hold off;
x=imcrop(I,BB);
y= imcomplement(x);
figure, imshow(y);
imwrite(y,strcat('D:\implementation\featurescrop\nose__',num2str(i),'.jpg'));
hold off;
end

size command always return 1x2 double data. for example if
BB = [168,253,79,48];
>> size(BB)
ans =
1 4
size(BB,1) gives only the first value of the output.
BB = [168,253,79,48];
>> size(BB,1)
ans =
1
So in your code loop is running for only first element.

As the size(BB,1) is 1, your loop runs only for once....As you said you are reading two images....change loop to:
for i = 1:2
%%%%
end
