Face Recognize – MATLAB (With Source Code)

-

As a beginner to MATLAB, I searched a source code for studying throughout the internet. But I could not find a complete source code for that. So, this is the source code for you who searching a MATLAB code for face recognize.



1.   Read Face
%%Reading Face & Class of the face
clc;
close all;
[fname, path] = uigetfile('.png','Open a Face as input for Training');
fname = strcat(path,fname);
im = imread(fname);
imshow(im);
title('Input Face');
c = input('Enter the class');


%%Extracting Features & Saving
F = FeatureStatistical(im);
try
    load db;
    F=[F c];
    db=[db; F];
    save db.mat db
catch
    db = [F c];
    save db.mat db
end


2.   Extracting Function
%%Creating FeatureStatistical.m
function [F]=FeatureStatistical(im)
im=double(im);
m=mean(im(:));
s=std(im(:));
F=[m s];
end

3.    Test Face
%%Reading Face
clc;
close all;
[fname, path] = uigetfile('.png','Provide a face for testing');
fname = strcat(path,fname);
im = imread(fname);
imshow(im);
title('Test Face');

%%Finding the class
Ftest = FeatureStatistical(im);

%%Comparing & Output
load db.mat
Ftrain = db(:,1:2);
Ctrain = db(:,3);
for(i=1:size(Ftrain,1))
dist(i,:)=sum(abs(Ftrain(i,:)-Ftest));
end
m = find(dist==min(dist),1);
det_class=Ctrain(m);
msgbox(strcat('Detected Class=' , num2str(det_class)));

C# Analog Clock

Today we are going to design analog clock as the first post in 2017. We can add digital clock to C# form very easily using “DateTimePicker”. Analog Clock cannot add like that. We must design it for our form. Let’s design an analog clock. First of all add a new form (Analog Clock) to your application. Next add a “pictureBox” and a “timer” to the form. As the next step write the following code. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Drawing.Printing; using System.Globalization; using System.IO; namespace Clock {     public partial class Form1 : Form     {         Bitmap bmp;         Graphics g;         Timer t = new Timer ();      int WIDTH = 100, HEIGHT = 100, secHAND = 50, minHAND = 50, hrHAND =  25;       int cx, cy;         public Form1()

Basic Prolog (List)

1.       How to find last element from a list Code: lastelement([A],A). lastelement([_|A],B):- lastelement(A,B). Output: lastelement([a,b,c,d],X). X = d . 2.       How to find n th element of a list Code: element_at(X,[X|_],1). element_at(X,[_|T],Y):- element_at(X,T,Y1), Y is Y1+1. Output: element_at(X,[a,b,c,d],2). X = b . 3.       How to check whether the element available or not Code: mem([X|_],X). mem([_|T],X):- mem(T,X). Output: mem([a,b,c,d],a). true .  4.       How to print all members Code: mem([X|_],X). mem([_|T],X):- mem(T,X). Output: mem([a,b,c,d],X). X = a ; X = b ; X = c ; X = d ; false. There is a “Prolog” keyword to find member of list. We can use it directly. 4.1. ?- member(X,[a,b,c,d]). X = a ; X = b ; X = c ; X = d. 4.2. ?- member(b,[a,b,c,d]). True 5.       How to find the length of the list Code: list_length([],0). list_length([_|T],X):- list_length(T,X1),X is X1+1. O

SOLID Principles

In Object-Oriented Programming (OOP) Concept, SOLID principles are the acronym for five Object-Oriented Design (OOD) principles. These SOLID principles are used to improve the understand-ability, flexibility and maintainability of the code.   S.O.L.I.D. Stands For? 1.      S - Single-responsibility principle 2.      O - Open-closed principle 3.      L - Liskov substitution principle 4.      I - Interface segregation principle 5.      D - Dependency Inversion Principle   Let’s see what is the exact meaning of each principle using an example. Ex: There is an online store. A registered customer can place an order and purchase them using the card or make payment when delivering the order. Let’s move to the principles again.   1.      Single-Responsibility Principle The common definition of this principle is “A class should have one and only one reason to change, meaning that a class should have only one job.” When we consider the above online store, there is a class
