draw jack little in matlab

To draw Jack Little's face using Matlab, we can use image-processing techniques to first detect the key facial features such as eyes, nose, and mouth. Here is an example code that uses the Viola-Jones object detection framework to detect faces and facial features:


main.m
% Load image of Jack Little
img = imread('jack_little.jpg');

% Create a face detector object
faceDetector = vision.CascadeObjectDetector();

% Detect faces in the image
bbox = step(faceDetector, img);

% Crop the face region for feature detection
face = imcrop(img, bbox);

% Create an eye detector object
eyeDetector = vision.CascadeObjectDetector('EyePairSmall');

% Detect eyes in the face region
bboxEyes = step(eyeDetector, face);

% Draw bounding box around the eyes
for i = 1:size(bboxEyes,1)
    rectangle('Position', [bboxEyes(i,1),bboxEyes(i,2),bboxEyes(i,3),bboxEyes(i,4)], 'LineWidth', 2, 'EdgeColor', 'red');
end

% Create a nose detector object
noseDetector = vision.CascadeObjectDetector('Nose','MergeThreshold',24);

% Detect nose in the face region
bboxNose = step(noseDetector, face);

% Draw bounding box around the nose
for i = 1:size(bboxNose,1)
    rectangle('Position', [bboxNose(i,1),bboxNose(i,2),bboxNose(i,3),bboxNose(i,4)], 'LineWidth', 2, 'EdgeColor', 'green');
end

% Create a mouth detector object
mouthDetector = vision.CascadeObjectDetector('Mouth','MergeThreshold',32);

% Detect mouth in the face region
bboxMouth = step(mouthDetector, face);

% Draw bounding box around the mouth
for i = 1:size(bboxMouth,1)
    rectangle('Position', [bboxMouth(i,1),bboxMouth(i,2),bboxMouth(i,3),bboxMouth(i,4)], 'LineWidth', 2, 'EdgeColor', 'blue');
end

% Display the annotated image
imshow(img);
