Nowadays, computer vision (CV) is essential and can be found almost everywhere. From cars (not only autonomous vehicles but in every modern car) to object detection in modern AI-fueled cameras. We can say that computer vision protects our safety and help us at work. But how this unique technology can be used in analyzing images? Let’s find out!

If you read our blog, you are certainly acquainted with computer vision. In general, it’s an AI-related technology that’s based on a set of cameras, sensors, applications, and algorithms that scan the surroundings or analyze images and videos. The range of applications of this technology is extensive, to say the least.

In fact, almost any kind of computer vision app is all about analyzing images. Usually, such an analysis happens in real-time (motor industry, security cameras). AI-fueled cameras and sensors scan everything and look for relevant elements or dangers. In this article, we are going to focus on analyzing images coming from cameras and sensors and see how this technology is used in modern computer vision applications and devices.

Analyzing images: The essence of computer vision

As you already know, analyzing images is the main role modern CV apps play. First of all, we have to talk about object detection. It’s a feature that focuses exclusively on detecting various objects in images, like, for instance, cats, cars, bikes, pedestrians, guns, workers, etc. Object detection is possible thanks to another AI-related technology: Deep learning. You see, the CV devices extract fragments of pictures and apply deep learning analysis to recognize patterns. One of the most advanced forms of object detection is face detection.

Why is it the most advanced form of CV? Primarily because faces have many different features and, in general, are quite similar. But there are tons of differences within, to name just skin color, hair color, glasses, haircut, hats, freckles, beauty marks, etc. The deep learning algorithm has to take all of these elements into account in order to identify a given person correctly.

The next important feature that helps in analyzing images is scene segmentation. Scene segmentation is all about outlining the object of interest. For instance, let’s say you have a security camera that monitors hundreds of people walking into the office building. Some of them walk in alone, some in groups. And this is where scene segmentation comes in handy. The CV camera can outline the suspicious or dangerous person (for instance, carrying a gun) and alert the security in the building.

One last feature that’s worth noting is 3D scene reconstruction. It’s also based on analyzing images. In fact, with a proper CV algorithm and a series of 2D images (taken from different angles), you can reconstruct a 3D object. This is how it works in modern GPS systems. When you’re driving in a city center with your GPS on, you can see 3D models of buildings you’re passing by. They are typically based on 2D pictures taken by drones, tourists, or GPS company employees.

DEEP LEARNING

As we’ve already said, the most complex and advanced CV algorithms utilize deep learning. It’s one of the most advanced AI-related technologies that works similarly to a human brain. Every piece of data (in our case, images and videos) goes through the multi-layered neural network, enabling analyzing images in a much more comprehensive way.

This solution, in turn, allows us to achieve a much higher level of complexity and accuracy. In other words, deep learning-fueled apps are much more thorough and accurate than standard CV devices.

Analyzing images: Real-life examples

Now, let’s take a closer look at some of the interesting real-life examples of analyzing images in computer vision.

ANALYZING IMAGES IN E-COMMERCE AND RETAIL

Computer vision applications help you maintain correct high-quality descriptions and pictures in your online store. It’s not a problem to devise a CV app that regularly scans your inventory in search of potential errors and mistakes. Such an algorithm can flag potential errors and mark them for further examination conducted by a human employee.

One of the most advanced applications of computer vision in retail are Amazon Go stores[1]. In such a store, there are no human employees. There are just CV cameras. The Go store’s cameras detect when you walk in, scan your cart, and detect when you walk out. Every customer in the store is continuously monitored. The deep learning network is used in order to assess who took what from which shelf.

RTG AT THE AIRPORT

We all know the situation: Every time you want to fly somewhere, you have to have your baggage screened with X-rays. Here, CV also plays a significant role. Of course, some human inspectors look at the screen, but computer vision algorithms aid them in work. By analyzing images, CV algorithms can detect dangerous objects and materials, such as explosives, guns, and drugs. It’s possible because the system produces cross-sectional tomographic images of a baggage’s content. It’s not only accurate but quick, too! The most advanced baggage screening stations can verify up to 500 suitcases per hour!

ANALYZING IMAGES FROM SECURITY CAMERAS

CV-fueled security cameras are more and more prevalent. Simply because they are much more efficient than typical surveillance cameras. Such a device can measure and monitor almost every desired element of the surroundings. For instance, security cameras can be teamed with thermal imaging in order to detect customers or employees with fever (a useful application for the COVID-19 times!). CV cameras can also detect guns or faces of people entering the building, thus helping maintain a high-security level. One of such cameras is Clevell One[2]. It’s a computer vision device combined with thermal imaging. It can be used to:

  • Detect potentially sick people
  • Registering working time
  • Detect employees’ faces
  • Detect hazardous materials and behaviors
  • Manage access (for instance, to various parts of the building)

REAL ESTATE VALUATION

Analyzing images from satellites allows insurers and real estate inspectors to view all the relevant property attributes at the time of underwriting. With computer vision, insurance companies are capable of validating property features, which accelerates the quotation process, mainly because it removes the need for physical inspections. One of such companies operating in this field is a property intelligence company called Cape Analytics. They provide insight into details about properties using structured data extracted from high-resolution imagery. Everything is fueled by computer vision and machine learning.

KYC VERIFICATION

This abbreviation stands for Know Your Customer. It’s a standard verification procedure conducted by the financial companies to register a new customer. In its traditional form, it takes several hours to complete. Thanks to computer vision, the entire process is shortened to just several minutes and happen with no human supervision.

One of the many banks that offer CV-fueled KYC verification is Citi. In this bank, you can open an account immediately. All you need is a photo of your ID document and your face. After submitting these files, the rest happens automatically. Citi’s computer vision algorithms analyze your pictures and, if everything is fine, your account is open. It can take just several minutes to finish the entire process.

ANALYZING IMAGES IN THE MOTOR INDUSTRY

Almost every modern car has computer vision-powered cameras that detect obstacles and dangerous situations, like, for instance, a pedestrian approaching a crossing. These cameras scan the car’s surroundings constantly and, if anything dangerous is about to happen, even before the driver may notice it, the CV systems can react and alert the driver. One of the companies developing such a system is Volvo[3]. They have developed a system called CWAB. In a situation where a collision is about to happen, these systems can use a full car’s braking power to stop the car and avoid the accident.

ANALYZING IMAGES IN THE MOTOR INDUSTRY

Another interesting application of analyzing images in the motor industry is number plate recognition. This solution is commonly used especially in speed cameras and car park systems. Number-plate recognition algorithms utilize character recognition and extract the text. For instance, such a system is used by the Unipark company. They use text recognition and extraction to manage cars driving in and driving out of their parking lots. When a vehicle approaches the barrier, the camera takes a picture of the license plate and sends it to the database. After verifying that the stoppage has been paid, the barrier automatically opens, and the car can drive out.

There are many more applications of this tremendous technology. For instance, analyzing images is extremely helpful in healthcare. This technology aids the surgeons’ and radiologists’ work. If you are interested in CV in healthcare, we recommend you read this article.
