srcFiles = dir('C:\Users\fit\Documents\MATLAB\H\*.jpg');  % the folder in which ur images exists
for i = 1 : length(srcFiles)
filename = strcat('C:\Users\fit\Documents\MATLAB\H\',srcFiles(i).name);
I = imread(filename);
I = rgb2gray(I);
I = im2double(I);
origin = I;
regions = detectMSERFeatures(I);
figure; imshow(I); hold on; plot(regions, 'showPixelList', true, 'showEllipses', false);

Use export_fig() and put it inside, not outside, your for loop.

Check your filename - is it different each time? Maybe put this after imshow():

drawnow;

Maybe also try closing the figure after you save it

close(f);

Thanks Image Analyst, I was solve my problem. Here it is. Dear Image Analyst, how to automatically crop out the MSER region area and paste in figure?

srcFiles = dir('C:\Users\fit\Downloads\Code\export figure\Arabian_Horses\*.jpg');  % the folder in which ur images exists
for i = 1 : length(srcFiles)
filename = strcat('C:\Users\fit\Downloads\Code\export figure\Arabian_Horses\',srcFiles(i).name);
I = imread(filename);
I = rgb2gray(I);
I = im2double(I);
origin = I;
regions = detectMSERFeatures(I);
f=figure(); imshow(I,'Border','tight'); hold on; plot(regions, 'showPixelList', true, 'showEllipses', false);
export_fig (sprintf('figure%d',i),'-jpg');
end
