% This method was setting to work with MUG dataset. If you will use another dataset. 
% Please check if (face, eyes, eyebrows, and mouth) regions are being detected correctly using he your_dataset_setting.m file.
% Maybe, you need to change some parameters (See the file readme)

%% read an input image and detect facial regions (face, eyes, mouth, and eyebrows)

clc; clear;

% read the input image
I = imread('face.jpg');
I = imresize(I, [224,224]);

[imgFace, LeftEye, RightEye, Mouth, LeftEyebrow,  RightEyebrow] = detectFacialRegions(I);
