Wide-angle cameras are increasingly being favored by smartphone manufacturers, from LG, recently to Samsung, and there are also rumors that the new iPhone generation is also equipped with this camera. Wide-angle camera will help us get full frame photos or group photos with no need to take a selfie stick. However, the weakness of this camera is the distortion in the corner, this affects a lot to the image quality, especially the selfie image because the face of the photographer will deform quite badly.
Fortunately, computer photography researchers are looking for ways to automatically fix face distortions when shooting with wide-angle cameras without affecting the rest of the image.
Applications like Adobe Photoshop can be used to correct distorted corners, but this requires certain skills. Most smartphone users are not too familiar with Photoshop, so researchers of MIT's Computer Science and Artificial Intelligence Laboratory have created an algorithm that can be added to any capture application. any photo to automatically correct distorted faces, without distorting other objects.
The distortion around the edges of a wide-angle shot can be corrected relatively easily, but in the process of editing may affect all objects in the middle of the frame. Modifying only the specific parts of the image is much more difficult, requiring researchers to create algorithms that identify areas of distorted faces, then this area will be used to limit processing. format when editing photos.

At the same time, the algorithm also ensures that the post-editing areas blend seamlessly into the surrounding areas of the unedited image, so that objects have straight lines, like the buildings behind a group of people, not broken or deformed.
All adjustments of the algorithm are fully automated, so users only need to click on a button in the photo editing application to fix. When the algorithm is fast enough, it can even be integrated into a photography application and apply wide-angle cameras to provide results almost instantly.
It is not known when such a function will appear on smartphones, but the researchers behind this algorithm are working for Google, so it is not surprising to see this algorithm appear first on Google Pixel in the future. hybrid
