Code: function varargout = Demo3(varargin) % DEMO3 MATLAB code for Demo3.fig % DEMO3, by itself, creates a new DEMO3 or raises the existing % singleton*. % % H = DEMO3 returns the handle to a new DEMO3 or the handle to % the existing singleton*. % % DEMO3('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in DEMO3.M with the given input arguments. % % DEMO3('Property','Value',...) creates a new DEMO3 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Demo3_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Demo3_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.

@@SergioZhink hi did you solve the problem ?because I have the same Error in gui_mainfcn (line 95) feval(Varargin{:}); Error in GUI_facedetection (line 42) gui_mainfcn(gui_State, varargin {:}); Please help me
Roynia Dewysen , this face detection using viola jones algorithm only! For details , you can refer this link-- in.mathworks.com/help/vision/ref/vision.cascadeobjectdetector-system-object.html Happy Learning :-)
