In this video, we discuss how to change screen color on mouse click. We used two design elements that are screen and button. A button tag is used to create the button. Javascript is used to change the screen color on mouse click that is HTML onclick Event attribute. We accessed the design elements that are button and screen using their id. document.getElementByID. A function is created to change the screen color by accessing the screen element. How to change text color on click using JavaScript? four steps are followed for Changing text color onclick: 1.)Define your Purpose. 2.)Choose Design Elements. 3.)Coding 4.)Run the Code Save filename.html Click on Run than Launch on Chrome

There is not 100% accuracy on masked face recognition. Algorithms like the viola-jones face detection algorithm can detect masked human faces from the digital images. I applied the viola jones algorithm on MASKED human face images and it successfully detects human masked faces. Link:  https://youtu.be/bgnb8kLhoWs https://youtu.be/bgnb8kLhoWs Face Detection Systems are used for the identification of a person from digital images. The face detection system can extract the different facial features from a digital image. A set of facial features extracted from a digital image includes eyes, nose, mouth, and face region. Face recognition is a difficult task due to the different facial expressions. With the help of a face detection system presence of a human face can be detected easily. For the detection of different facial features, the Viola-Jones algorithm is used in the proposed work. To make the task more manageable, Viola-Jones requires full view frontal upright faces.

First, learn about FACE DETECTION.  Then face recognition would be an easy task for you. Because most of the computer algorithms work first on face detection after that they can recognize. First learn, how to detect humans or anything you want to detect (objects/ birds/other). When your software will be able to detect it. Then train it for recognition. I worked on Human face recognition. First, I created software for human face detection. Once your software can detect it. You can easily train it for recognition/identification.

There are already several efforts in place to leverage artificial intelligence in the fight against coronavirus. Some of these methods include automatically measuring people’s temperature in public places, diagnosing COVID-19 infections from chest x-ray scans, and using machine learning algorithms to predict the spread of the virus. 1.)

C++ Program to Calculate Area of Rectangle using Objects and Classes. Calculate Area of Rectangle: Area = Length x width - In C++, we are using Objects and Classes to calculate the area of the rectangle. The syntax of a class specification is given below: class classname { private: data_members; member_function; public: data_members; member_function; }; The syntax for creating objects of a class is: classname object1, object2, object3,…,; Video Explanation: How the Program is working.

Array Instillation Program

MATLAB Simulator Q . Why we are using simulation software? A. Simulation Software helps us to predict the behavior of a system (i.e., Dynamic System ).  Q. How we can use simulation software? A. We  can use simulation software to evaluate a new design, diagnose problems with an existing design, and test a system under conditions that are hard to reproduce, such as a satellite in outer space.   Q.  Who using Engineers simulation software and why?  A.  Engineers and scientists use simulation software for a variety of reasons.  Creating and simulating models is less expensive, t o  t est different designs  before building one in hardware and  to test the integration of the full design.  Q.  What is  Simulink? A. A  simulation and model-based design environment for dynamic systems  integrated with MATLAB.  Simulink is developed by MathWorks. Q.  Why    Simulink is used? A.  Simulink is used for  modeling, simulating and analyzing multi-domain dynamic systems.  it is a 

Arguments Passing Techniques C++ is the mother of Object-Oriented Programming. Arguments Passing is a Process of transferring data between the calling function and the called function. In C++,  there are three ways by which arguments can be passed. Pass By Value Pass By Address or Pass By Pointer Pass By Reference Video Explanation:  C++ Program to swap two numbers with the third variable.     https://youtu.be/pq9VWQswqwo Video:  Call By Value Most of the programming languages like C use only the first two modules (i.e., Passing by Value and Address) whereas C++ supports all the three methods of passing arguments. Pass By Value: It is a default method for argument passing. When an argument is passed by value than a copy of the argument is made and passed to the newly created formal arguments in the called function. The formal arguments contain a copy of actual arguments which is stored in the separate memory location.   Program to Show How Pass By Value Work
