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?

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