Estimating the Size of a Crowd with OpenCV and a Raspberry Pi 4 2, image processing with opencv and RPi4, opencv RPi4, Rpi4 openCV, crowd size with RPi4, crowd size with image processing, crowd size with opencv
Welcome to the next tutorial on our raspberry pi four python programming. In the previous article, we built a system that recognizes when two people are in physical contact using OpenCV and a Raspberry Pi 4. We used the weights from the YOLO version 3 Object Recognition Algorithm to implement the Deep Neural Networks part. Regarding image processing, the Raspberry Pi consistently comes out on top compared to other controllers. A facial recognition program was among the earlier attempts to use Raspberry Pi for sophisticated picture processing. In today's world of cutting-edge technology, digital image processing has expanded rapidly to become an integral feature of many portable electronic gadgets. Digital image processing is widely used for such t ...

Introduction to Arduino Leonardo
Introduction to Arduino leonardo, Arduino leonardo features, Arduino leonardo pinout, Arduino leonardo pin description, applications
Hi Guys! Hope you are getting along with life pretty well. I always strive to keep you updated with most valuable information related to engineering and technology. Today, I'll discuss the detailed Introduction to Arduino Leonardo. It is a microcontroller board based on the ATmega32U4 and comes with 23 digital input/output pins. It is developed by Arduino.cc, aiming to provide easy to use interface with the ability to perform a number of functions on a single chip. It incorporates everything required to drive the automation in the relevant project. Simply connect this device with the USB cable or power it up using DC adapter and start playing with it In this post, I'll try to cover each and everything related to Arduino Leonardo, so you don't n ...

Hey Fellas! We always strive to keep you updated with best and valuable information so you keep coming back for what we have to offer. Today, I am going to uncover the details on the Introduction to 7805. It is a positive voltage regulator used for providing constant output voltage over a wide range of input voltage. Before we move on, you must be clear what is voltage regulation? Voltage regulation is referred as the measure of voltage change between input and output. The IC 7805 does the same thing. It provides constant output voltage when a range of different voltage is applied at the input terminal. This component comes with three terminals called input, ground, and output. This is called positive voltage regulator because it generates posi ...

Color Detection in Images using MATLAB
color detection in matlab,matlab color detection,color detection matlab,detect color matlab,detect color in matlab
Hello friends, hope you all are fine and having fun with your lives. In today's tutorial, we are gonna see Color Detection in Images using MATLAB. In the previous tutorial, I have posted about How to Detect Circles in Images using MATLAB in which we have detected objects based on their geometrical figure means either they are circle or not but today we are gonna distinguish objects based on their color i.e. whether they are red colored or green colored etc. Its a quite simple tutorial and comes in the basic category. We will first detect the color and then will create a boundary around that object and will also show its XY coordinates as well. Image processing is an important tool of MATLAB. We can quite easily do the image processing in it using ...

Types of Fluid Flows
Types of flow, types of fluid flow, Steady and Unsteady Flow, Uniform and Non-Uniform Flow, One, two and three-dimensional Flow, Rotational or Irrotational Flow, Laminar and Turbulent, Compressible and Incompressible Flow
Hello Friends. I hope you are doing great. Here I am with another exciting topic of fluid mechanics, i.e. flow over bodies. In this article, I will explain the flow of fluids, the flow rate, their nature, the flow in pipes and much more. Fluid mechanics is all related to the fluid and its nature. I will discuss the forces that are on the body that is immersed in a fluid and the flow that is over the body. As the title shows, the main emphasis will be on the lift and drag forces. Moreover, the external and the internal flow will also be discussed in this article. And I am sure that you will enjoy reading this article. So without wasting any time, let us start. I will start with an introduction to fluid flows. Introduction In this article, our focus will be the fluid flow over the bodies ...

How to use C# array
c# array, C# arrays, array c#, how to use c# array, c# array use, array in c#
Hello everyone, hope you all are fine and having fun with your lives. In today's tutorial, we are gonna have a look at How to use C# Array. C# array is quite a simple concept but students normally got confused while using C# array that's why I am gonna explain it in a detail. C# array is used to store similar data in a single variable. Let me explain this with an example. Suppose you have 10 integer variables then what you need to do is to save all of these 10 variables in separate C# Int variables which will not only increase the size of your code but will also make it quite complex. So, instead of creating 10 separate C# Int variables you can simply create a single C# array and can add all of them in it. Let's take an example for C# arrays from ...

Virtual Private Network (VPN) - All you need to know
VPN, Virtual Private Network, guide for VPN, VPN Guide,Virtual Private Network Guide
You must have heard about the VPN. It's a much common phrase these days. Many teenagers use this service to browse online, stream the content and get the location prohibited services online, but the actual meaning of VPN is a lesser-known fact and why VPN was introduced is rarely known. In this complete guide about VPN, you'll learn everything about the VPN- the intro, history, usage, types and benefits. Introduction to VPN VPN is pronounced as Virtual Private Network. As its name suggests, VPN is a private network connection that serves the purpose of data sharing, privately, among several connected devices. All the computers, mobiles, laptops and other devices connected through this virtual private network can share the data with secured encrypt ...

In today's tutorial, we are gonna add some validations on the data provided by the users in those Text box fields. We will place some constraints like the age must be above 13 or the characters of name must be between 4 to 20. So, let's have a look at How to deal with Validation in ASP.NET MVC: Validation in ASP.NET MVC Validation uses built-in attribute of ASP.NET called DataAnnotations and is used to validate inputs provided by the user. Validation is a very ...
