If you ever need an example of the exponential growth of technology, defy the digital camera. In less than 25 years, the ability to capture an image on an electronic sensor has transformed the way we understand photography and how we preserve precious (and not-so-precious) moments in life. In this article, the author of the write my work 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 come in handy for visually training employees. Employees can go through a step-by-step search with connecting devices in the company to quickly and safely improve the required skills.
Virtual worlds are not easy to design, but the result is worth the effort. Some experts believe that the tool will help you learn new skills faster through the effect of presence. To create a virtual reality, experts study the audience’s requests, analyze what the image will look like on both screens of glasses and find ways to prevent the motion sickness that can manifest itself in some users. Also, experts intentionally create videos that last no more than half an hour. In her opinion, the user does not lose concentration during this time.
2. Virtual Dressing Rooms.
If 20 years ago customers were rating things that were on the mat in the market tent, today it is no longer necessary to leave the house to choose clothes. Augmented reality can help determine if a shirt, jeans, shoes, and even makeup fit you.
All you need to try them on 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 “fit”, the neural network finds the key points where the image needs to be transmitted. This way you can’t judge whether the shoes are comfortable, but you can guess how they will fit into your wardrobe.
3. Celebrity Revival and Holographic Shows
The technology that allows celebrities to perform from the comfort of their own homes dates back to the mid ’90s and is constantly improving. Viewers saw Kate Moss perform at one of the Alexander McQueen shows and watched virtual singer Miku Hatsune, who still gives concerts. Late celebrities such as Whitney Houston, Roy Orbison and Amy Winehouse can also be seen on the stage. A holographic performance is similar to a film session: a person’s video is projected onto the thinnest foil.
This use of technology has its detractors, who “label” such events as digital necromancy. At times, celebrities even prohibited the use of their images after death. Robin Williams, for example, did just that. In contrast, some actors try to make digital copies while staying in their prime. And sometimes they even sell the copyrights to copy themselves and provide for their heirs later.
4. Face and product recognition at counter
You probably use similar technology every time you disable your smartphone’s lock. Video surveillance systems use a similar technique for streets, retail, and industrial campuses.
Face recognition helps protect citizens from threats, detect shoplifters and locate missing persons. This option allows you to pass through a turnstile or pay for purchases at the checkout. While facial recognition on smartphones works with a single owner of the device, public place technology can interact with dozens of passers-by at once. The system reads the main points on faces: eyes, nose and mouth. Then the neural network compares them to the database and finds matches to specific people.
Video analysis can also be helpful for the timely replenishment of groceries in supermarket sales rooms. The algorithm detects empties on the shelves, collects data on missing goods and sends notifications to store employees.
5. Ability to change background during a call
Finding a suitable background for a call can be challenging for those working from home. To avoid conducting business conversations against a rug, a video messenger user can blur what is behind them or set a neutral image.
Many apps use roughly the same method 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’s a catch with background replacement. Although this option is implemented in much the same way as blur, application creators find that it shows itself best with a green screen. It helps the artificial intelligence not to be distracted by the high-contrast background behind the user and provides the most precise image possible. However, if you don’t have a unique green screen, you can try sitting against a monochrome wall.
