If you ever need an example of the exponential growth of technology, brave the digital camera. In less than 25 years, the ability to capture an image on an electronic sensor has changed the understanding of photography and the way we preserve precious (and not so precious) life moments. In this article, the writer from the write my paper service tells us the five most amazing things video technology has done for us.
1. Learning in Virtual Space
The combination of video technology and virtual reality is actively used in the oil industry. For example, VR materials are convenient for training employees visually. Employees can go through a step-by-step quest with connecting devices at the company to quickly and safely hone the necessary skills.
Virtual worlds are not easy to design, but the result is worth the effort. Some experts believe the tool helps you learn new skills faster through the effect of presence. To create virtual reality, experts study audience requests, analyze how the image will look on both screens of glasses, as well as find ways to prevent motion sickness, which can manifest itself in some users. In addition, experts intentionally create videos that last no more than half an hour. In their opinion, the user will not lose concentration during this time.
2. Virtual dressing rooms.
If 20 years ago customers evaluated things standing on the mat in the market tent, now it is not necessary to leave home to choose clothes. Augmented reality can help determine if a shirt, jeans, shoes, and even makeup fit you.
To try things on, all you need is your smartphone. For example, the customer must turn on the camera and point it at their feet to assess what a new pair of sneakers would look like. For a realistic “fitting,” the neural network finds the key points where the image needs to be transferred. This will not allow you to assess whether the shoes fit comfortably, but you can guess how they will match your closet.
3. Celebrity Revival and Holographic Shows
The technology that allows celebrities to perform in the comfort of their homes dates back to the mid-’90s and is steadily improving. Viewers watched the performance of Kate Moss at one of the Alexander McQueen shows and watched the virtual singer Miku Hatsune, who still gives concerts. Even deceased celebrities such as Whitney Houston, Roy Orbison, and Amy Winehouse can be seen on stage. A holographic performance is similar to a movie session: a person’s video is projected onto the thinnest of films.
This use of technology has its detractors, who “call” such events digital necromancy. At times, celebrities even forbade the use of their images after death. Robin Williams, for example, did just that. In contrast, some actors seek to create digital copies while they remain in their prime. And sometimes, they even sell the copyrights to copy themselves to provide for their heirs later.
4. Face and Product Recognition at the Counter
You probably use a similar technology every time you turn off the lock on your smartphone. Video surveillance systems use a similar technique for streets, retail, and industrial premises.
Facial recognition helps protect citizens from threats, track shoplifters, and locate missing persons. This option allows you to go through a turnstile or pay for purchases at the cash register. While facial recognition on smartphones works with a single owner of the device, the technology for public places can interact with dozens of passersby simultaneously. The system reads the main points on faces: eyes, nose, and mouth. Then the neural network compares them with the database and finds matches with certain people.
Video analytics can also come in handy for the timely replenishment of groceries in supermarket salesrooms. The algorithm detects empties on the shelves, records data on the lack of goods, and sends notifications to store employees.
5. Ability to change the background during calls
Finding a suitable backdrop for a call can be challenging for those working from home. To avoid having business conversations against a wall rug, a video messenger user can blur what’s behind him or set a neutral image.
Many apps use roughly the same methodology for calls. Artificial intelligence finds the person and separates them from the background. The algorithm is trained to distinguish all body parts and details down to the hair. Background blur works in almost all conditions, but there is a snag with background replacement. Although this option is implemented in about the same way as blur, the creators of the applications note that it shows itself best with a green screen. It helps the artificial intelligence not to be distracted by the contrasting background behind the user and provides the most precise picture possible. However, if you do not have a unique green screen, you can try to sit against a monochrome wall.
