operator overloading

■ operator overloading
• Operator overloading gives the ability to use the same operator to do various operations.
• It allows you to define how operators work with your custom types (classes or structs).
• This can make your custom types more intuitive and easier to use.

Let's say we have a Complex class to represent complex numbers. We want to overload the + and - operators to add and subtract complex numbers.


    Example :-
_____________________________
public class Complex
{
    public double Real { get; }
    public double Imaginary { get; }

    public Complex(double real, double imaginary)
    {
        Real = real;
        Imaginary = imaginary;
    }

    // Overloading the + operator
    public static Complex operator +(Complex c1, Complex c2)
    {
        return new Complex(c1.Real + c2.Real, c1.Imaginary + c2.Imaginary);
    }

    // Overloading the - operator
    public static Complex operator -(Complex c1, Complex c2)
    {
        return new Complex(c1.Real - c2.Real, c1.Imaginary - c2.Imaginary);
    }

    // Overriding ToString method for better output representation
    public override string ToString()
    {
        return $"{Real} + {Imaginary}i";
    }
}

class Program
{
    static void Main()
    {
        Complex c1 = new Complex(1.0, 2.0);
        Complex c2 = new Complex(3.0, 4.0);

        Complex sum = c1 + c2;
        Complex difference = c1 - c2;

        Console.WriteLine($"Sum: {sum}");
        Console.WriteLine($"Difference: {difference}");
    }
}

Raster scan Vs Vector Scan

1. Raster Scan Display   How It Works : A raster scan display works by painting an image on the screen pixel by pixel, row by row. It follows a systematic pattern where the electron beam (in CRT monitors) or the display elements (in modern LCD/LED screens) sweep across the screen from left to right, top to bottom, in a series of horizontal lines (scan lines). This process is akin to how a traditional TV screen works.   Process : The display draws the image starting from the top-left corner, moving to the right, then moves to the next row below, and repeats this process until the entire screen is filled. This pattern creates a grid of pixels, where each pixel can have a color and brightness level.   Characteristics : Pixel-based : The screen consists of a grid of pixels, and each pixel can have a distinct color and intensity. Continuous Image : Raster scan displays are capable of displaying detailed and complex images, including photographs and videos, because they break t...

Inheritance

*■ Inheritance*  • Inheritance is a concept in OOP that allows a class to inherit properties and behaviors (methods) from another class. • A class that inherits from another class is called a derived class (or subclass) • The class which gets inherited by another class is called the base class (or superclass). • Inheritance is possible only if there is is-a relationship between parent and child class. • constructors are not inherited in derived class, however the derived class can call default constructor implicitly and if there's a parameterised constructors in bass class then derived class can call it using 'base' keyword.  ____________________________________________  *➤ Rules of Inheritance*  1) C# supports single inheritance, meaning a class can inherit from only one base class. 2) A parent class constructor must be accessible in child class otherwise  inheritance will be not possible. 3) every class, whether user-defined or predefined implicitly derives fr...

unit -1 Introduction of Image processing

  What is Image Processing? Image processing is a method to perform operations on an image to enhance it or extract useful information. It is a type of signal processing where the input is an image, and the output may be either an image or characteristics/features associated with that image. Goals of Image Processing Image Enhancement : Improving visual appearance (e.g., contrast, sharpness) Image Restoration : Removing noise or distortion Image Compression : Reducing the amount of data required to represent an image Feature Extraction : Identifying objects, edges, or patterns Image Analysis : Understanding and interpreting image content Object Recognition : Detecting and identifying objects in an image What is an Image? An image is a two-dimensional function f(x, y) , where x and y are spatial coordinates, and f is the intensity (brightness or color) at that point. For digital images, both x, y, and f are finite and discrete. Types of Image Representation...
