Image Search using Guide in MATLAB

Inorder to run the below code , place the images of actors in actors folder,
images of actress in actress folder,images of dogs in dogs folder and place all these folders on your computer desktop

Type Guide in matlab and create a GUI as shown below and save it on desktop

Run it,
You will get below code in green automatically generated
Copy and paste the code in black to the automatically generated code.
run the code in MATLAB
 function varargout = untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
%      UNTITLED, by itself, creates a new UNTITLED or raises the existing
%      singleton*.
%
%      H = UNTITLED returns the handle to a new UNTITLED or the handle to
%      the existing singleton*.
%
%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UNTITLED.M with the given input arguments.
%
%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before untitled_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

You will get output as shown below

making a video out of images in matlab

=====================In older versions of MATLAB========================

samples_dir='C:/data'; % data is folder name that has images

files = dir([samples_dir , '\*.jpg']);
aviObj = avifile('C:\test.avi', 'Compression', 'MSVC'); %test.avi is the name of the video and gets stored
%addframe cannot be used for true color images, so convert to gray scale and then add 

%video quality is not good

for i=1:length(files)
f_bmp=[samples_dir '\' files(i).name];
img=imread(f_bmp);
gr=rgb2gray(img);
aviObj = addframe(aviObj, gr);
end
aviObj=close(aviObj);

===================In newer versions of MATLAB===========================
 clear all;
close all;
samples_dir='C:/data'; % data is folder name that has images

Files = dir([samples_dir , '\*.jpg']);

VideoFile='C:\data\MyVideo'; %path of the video file to be saved
writerObj = VideoWriter(VideoFile);
writerObj.FrameRate =1; %increase the frame rate, here i have used 1 frame per second
open(writerObj);
for t= 1:length(Files)
Frame=imread(strcat('C:\data','\',Files(t).name));
writeVideo(writerObj,im2frame(Frame));
end
close(writerObj);

%To play the video

videoFReader = vision.VideoFileReader('C:\data\MyVideo.avi');
videoPlayer = vision.VideoPlayer;
while ~isDone(videoFReader)
   frame = step(videoFReader);
   step(videoPlayer,frame);
end
release(videoFReader);
release(videoPlayer);
                                                  (or)
implay('C:/data/MyVideo.avi');
