Count Coin Values in Image using MATLAB

-
As the first step, I am going to read the image.
             img = imread('F:/Academic Video/MC/PracticalAssignment_I/Coins.jpg');

As the second step, I am going to crop the image.
            img1 = img(700:2500,400:1950,:);
As the third step, I am going to convert the image into black and white
            bw = im2bw(img1);
As the fourth step, I am going to convert the background color into black and object color into white.
            bw = ~bw;
As the fifth step, I am going to enhance the objects.
            se = strel('disk',50);
            img2 = imdilate(bw,se);


            img2 = imerode(img2,se);
            se = strel('disk',60);
            img2 = imerode(img2,se);
As the sixth step, I am going to get the count of coins.
            [L N]=bwlabel(img2);
            N
            N =

                   8
As the seventh step, I am going to label the coins. (text(X coordination ,Y coordination,value))

t = [text(344,1039,'1'),
text(300,712,'2'),text(475,283,'10'),text(596,1513,'2'),text(785,766,'2'),text(1055,322,'5'),
text(1142,1510,'10'),text(1172,913,'1')];



See the label in the figure without using imshow(img2).

As the last step, I can get the summation of the values.
      sum =0;
      for x=1:N
      sum = sum+(str2num(t(x).String));
     end
     sum
     sum =
               33

C# Analog Clock

Image
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
