Government organizations can implement computer vision in smart cities to maintain social distancing and avoid stampedes and other disasters in crowded areas.
As the global population continues to grow at an alarming rate, crowd management becomes an increasingly challenging task. The global population is reportedly projected to reach 8 billion in 2025. Global trends also indicate that the population in urban areas has been growing steadily over several years. This suggests crowd management can be even more difficult in urban areas. Government organizations can tackle this issue effectively by developing smart cities that use multiple cameras, low-power sensors, and artificial intelligence. Combining these tools with computer vision can make smart cities even more advanced. By implementing computer vision in smart cities, governments can precisely monitor public places and create strategies for effective crowd management.
Government organizations and authorities can use computer vision in smart cities to identify people and objects, assess the motion of vehicles and predict congestions, detect crowded areas, and more. Furthermore, computer vision applications will offer real-time insights that will assist governments in making decisions for smart cities. Smart cities are already benefiting from computer vision by implementing smart parking systems and maintaining law and order. Crowd management will be another major use case for computer vision in smart cities.
Applications of Computer Vision in Smart Cities
Here’s how governments can utilize computer vision in smart cities:
Maintaining Social Distancing
Ensure Social Distancing Since the beginning of the COVID-19 pandemic, healthcare experts around the world have advised us to ensure social distancing of at least 6 ft along with wearing masks. However, it can be quite difficult to maintain social distancing in crowded cities. In this case, smart cities can use computer vision to plan their infrastructure to ensure social distancing in crowded places. For instance, Numina has developed a computer vision-powered tool that offers multi-object tracking in smart cities. The company had tweeted a video that shows how New Yorkers were trying to practice social distancing, but the narrow sidewalk space made it a daunting task. Governments can use such real-time data to identify issues that could be overlooked.
Avoiding Stampedes in Crowded Areas
Government organizations can use computer vision in smart cities to monitor crowded events like concerts and live sports venues where chances of stampedes are quite high. In these scenarios, computer vision will provide real-time estimates like the number of people and crowd density. Such data can be used to avoid stampedes and other disasters as well as assist in controlling the crowd.
Although the implementation of computer vision in smart cities can be effective in crowd control, many of us would be concerned about the invasion of privacy. Citizens of most countries will be worried about their governments using advanced technologies to gather real-time visual data about them. To address this issue, governments need to develop a proper framework to ensure that sensitive data can be accessed only by select high-level officials and that such data will not be misused.
The Best Programming Languages for Web Services and Their Advantages In 2022
The world is becoming more digital, and the need to learn digital skills is higher now than ever before. One such digital skill that has gained more prominence since the last decade is programming languages. We now live in a world revolving around technology, and basic knowledge of programming languages is becoming a necessity for many career options and job profiles.
There are many reasons to learn about the different programming languages and their advantages, and web services or web development is a big part of it. Web development is an ever-growing field and has plenty of opportunities. To grab these opportunities in web development, you need to equip yourself with the correct programming language. However, the plethora of language options available to you can be confusing, especially if you are a beginner.
This high-level language, often used by most websites as a client-side language, is a core technology in the World Wide Web. Initially, it was used only for developing web browsers; however, they now have new usages in non-web browser applications and server-side website deployments.
Since its creation in 1995, it has evolved into one of the world’s most popular programming languages and is highly sought after by various organizations.
- It is very popular and is everywhere on the net.
- It can run immediately in the client-side browser.
- It doesn’t demand much from the website server.
- Different browsers may interpret it differently sometimes, so writing cross-browser code is difficult.
This is a powerful programming language and is one of the best used in web development for multiple purposes. Furthermore, this open-source language is very easy to learn and deploy and is among the best languages for learning web development since it develops scalable applications and web pages.
Python has a unique selling point: the simple, productive, and elegant design of this language. It is the best for backend development with first-class integration with other programming languages such as C++ and C.
Python has numerous usages, especially in developing web and desktop applications and GUI-based applications such as machine learning, data science, and network servers. It also offers multiple toolsets for mathematics, statistics, and computational science with numerous libraries and frameworks like NumPy, Pandas, SciPy, and Scikit-Learn.
- It increases the productivity of programmers and developers.
- It supports several systems and platforms.
- It follows object-oriented programming.
- It ensures easy scalability, even with complex web applications.
- Offers numerous support libraries.
- It focuses on code readability.
- The database is primitive and slightly underdeveloped.
- Not ideal for mobile computing.
HTML stands for HyperText Markup Language. This language is the foundation upon which web development is built, and every developer must familiarize themselves with it. It is a very popular language and is currently one of the most used programming languages. While it cannot be described as a full-fledged programming language, HTML is the standard language for creating web pages.
HTML gives web pages structure and ensures that images and texts are correctly formatted. In addition, it is a fast language and helps developers design web pages much quickly because it uses templates.
- Learning and implementing is easy.
- It is free and accessible.
- All browsers support it.
- This language is static, so creating dynamic pages is impossible.
- It requires lots of code to develop a simple webpage.
PHP is highly productive in web development and is used vastly within this industry to build and deploy applications quickly.

- It uses the Xdebug extension, which allows for great debugging.
- It has a large ecosystem with incredible community support.
- It doesn’t have features for handling errors and security.
- It is slower to build a web page using this language alone than other programming languages.
CSS is similar to HTML because it is also a basic language that all developers should know. CSS is the acronym for Cascading Style Sheets. This language is mainly used along with HTML to govern a web page’s style. Combining CSS and HTML languages is often the mother of programming languages. For example, CSS determines the color, positions, and size of elements within a webpage.
CSS uses a cascading style, which means an applied style cascades down from the parent to the child throughout the web page. This cascading nature allows it to uphold consistency.
