From now on, Twitter will crop the image and use a technique called Saliency. Saliency indicates an important area on the image that viewers often focus on. Researchers say people often pay attention to faces, text, animals and areas with high color contrast.
Twitter's neural network is learning to find the most interesting part of the photo in a short time so that users do not realize the delay when posting photos.
