NEC introduces 'ultra-resolution'

Japan's NEC announced today that it is developing a super-resolution " super-resolution" technology that magnifies the images several times while retaining sharpness and detail. body, such as the face or license plate.

The company plans to use the new technology for traffic censors and says it can enlarge images of objects by four times, but the image is still clear.

In order to enlarge the image, one has to use various static images extracted from a video to enhance the resolution of the image. However, this method has the disadvantage that the image will be blurred when launched 2 or 3 times.

Meanwhile, the new technology NEC is talking about is a single image that can be enlarged up to four times (the number of pixels will increase by 16 times), but still retain the detail of the image, for example. like small or distant objects. So this technology is very suitable for traffic cameras or CCTV at airports, train stations ...

The principle of this "super sharp" technology is that it uses a library of (or databases) of different resolution images for image processing, and It automatically selects the highest resolution image that matches the subject to be enlarged. In addition, it also removes the excess images to save space on the database.
