At the moment this code detect eyes and mouth in separate images, how can i combine these facial parts in 1 image, does anyone know how i would combine these features and output them in a single image.
Thankyou
%Read the input image I = imread('extract1.png');
%To detect Mouth
MouthDetect = vision.CascadeObjectDetector('Mouth','MergeThreshold',16);
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
title('Mouth Detection');
hold off;
%To detect Eyes
EyeDetect = vision.CascadeObjectDetector('EyePairBig');
BB=step(EyeDetect,I);
figure,imshow(I);
rectangle('Position',BB,'LineWidth',4,'LineStyle','-','EdgeColor','b');
title('Eyes Detection');

Just don't create a second figure like you're doing. Use the same figure and hold on.

the above algo detects the regions by surrounding them with the rectangle regions...how to display the rectangular regions separately?...any code for automatically cropping that region and display it separately?

That's not how it detects them. That's how it indicates them so you can see what it found, after they've been detected. You can crop out the sub image like this:
subImage = imcrop(I, BB); % Crop box BB out of image "I".

x = imcrop(I,BB(i,:));
imshow (I)
this would work and solve your problem ;)
