How to Correct Wide Angle Distortion on Photos and Videos
Google has developed an algorithm together with MIT to correct the wide angle distortion issue occurring on photos. Unlike AI technology devotes to repair grainy parts of a photo to reach its restoration purpose, Google's new technology runs differently: in a simple word, the algorithm detects the distortion parts of a photograph, locates and rectifies them. Then to some extent the rectified picture will look like as good as the normal one.
The whole correction process can be fulfilled by adding one magic filter. You don't hear me wrong, just one filter. That's all needed to correct your distorted wide angle images. Therefore, if you have some distorted pictures on hand and do not want to delete them for some memorable reasons, this post will be the guider of your picture-rescue-operation. Keep reading.

Google's Wide angle Distortion Correction Technology
Google's new algorithm is developed from one of its previous researching projects. In its previous program, the operation processes this way: the user may send images in a low-resolution from one mobile phone to the server, then the server will send user back with a 'converting method' on those images, and users are allowed to convert those images to the high-resolution ones in their mobile phones manually. This project is designed for emitting on bandwidth consumption in the first place.
How Google's previous program acquires information on color pixels:
Step #1. To endow the system with the ability to detect the output results through a set of formulas, apply for correcting pixel colors of images, rather than pure images that are learned by the computer.
Step #2. The system will automatically output a 16*16*8 three-dimensional grid, in order to apply these formulas in high-resolution images. In the 16*16 grids, each rectification formula is included by every single grid.
As is developed from such a good project, Google's new technology has little possibility to be a joy-killer. And looking from its official news release, it surely is not disappointing.
Comparisons between the previous photo and its corrected result:
Each coin has its two sides. Although this technology has everything positive for photographers, for the time being, it has its dark sides as well. The problem is, according to tech geeks, whether it will perform well in the streaming occasions too, for example, in live streaming or video meeting and they list their worries about the incompatibility of speed between correction streaming and live streaming:
-"I am a photographer, and I record as well rather than solely taking pictures. This technology has everything I want for fixing my distorted pictures, however, it cannot do the same thing to rescue my distorted videos, which is quite disappointing for me."
-"Google's technology will be awesome for me if it can work for correcting barrel distortion of my video clips."

Photo restoration has no longer been a problematic issue that bothers photograph enthusiasts nowadays. We now enjoy a much more convenient digital life than ever before thanks to various technologies developed. On the one hand, with the development of AI photo restoration and Google's wide angle distortion correction algorithm, photographers are rescued from image correction. On the other hand, having video distortion correction software developed to handle barrel distortion pincushion distortion and mustache distortion, more video filming lovers can benefit from video correction as well.
