%% To detect Face

%Read the input image
Img = imread('2.jpg');

%Returns Bounding Box values based on number of objects
Face = step(Face_Detect,Img);

%% To detect Nose
Nose_Detect = vision.CascadeObjectDetector('Nose','MergeThreshold',16);
Nose = step(Nose_Detect,Img);
figure,
imshow(Img); hold on
for i = 1:size(Nose,1)
    rectangle('Position',Nose(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','b');
