How to crop a detected face and face parts and save them as separate images?

I am using the detectfacepart code of the following link ( http://www.mathworks.in/matlabcentral/fileexchange/36855-face-parts-detection) for detecting the face and face parts. How can I crop the detected face and face parts and save them as separate images?

[Dibya]

Sorry but I could do it myself.

For example;

leye = imcrop(img, bbox(:, 5: 8));

figure;imshow(leye);

imwrite(leye,'leye.jpg');

Here is the code for

1. Select image from a Location
2. Detect faces in the selected image
3. Find the Location of Detected Faces
4. Crop all detected faces on one Figure

%Code start

clc; 
[filename, folder] = uigetfile ({'*.jpg';'*.bmp';'*.png'}, 'File Selector'); 
fullFileName = fullfile(folder, filename); 
img = imread(fullFileName); 
figure(1);
imshow(img); 
FaceDetect = vision.CascadeObjectDetector; 
FaceDetect.MergeThreshold = 7 ;
BB = step(FaceDetect, img); 
figure(2);
imshow(img); 
for i = 1 : size(BB,1)     
  rectangle('Position', BB(i,:), 'LineWidth', 3, 'LineStyle', '-', 'EdgeColor', 'r'); 
end 
for i = 1 : size(BB, 1) 
  J = imcrop(img, BB(i, :)); 
  figure(3);
  subplot(6, 6, i);
  imshow(J); 
end

%Code End

hey.. thank you, it was helpfull to my project

[lolo mustafa]

thanka a lot

its worked but I want to ask about something

[Image Analyst]

OK, so go ahead in your own question (rather than use Dibya's thread), but AFTER you read this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

may this code helpful formore than 1 images???

means ihave todetect face for almost thousands images. is thiswork in loop??

[Image Analyst]

Sidra, of course. See the FAQ

i want to proposed to work lip detection from image sequence , but know i cant preprocessed several image file

• how to detect multi face image using loop
• how to crop then and stror new dir for farther processing

Make sure you're passing [leftColumn, topRow, numberOfColumns, numberOfRows] as the second argument to imcrop. I'm not sure what you're passing. If you pass the right thing, it will work.

[Dibya]

Thanks for your response. Yes,the bbox(:,5:8) contains the bounding box i.e (xmin,ymin,width,height)for left eye in that example.

[Image Analyst]

I don't think it does, because you have : which means "all rows" so there is likely more than 4 numbers there. Try this before you call imcrop():

croppingRectangle = bbox(:, 5:8)  % No semicolon
whos croppingRectangle

and tell us what it says.
