Abstract
The present disclosure relates to an image restoration system that efficiently and accurately produces high-quality images captured under low-light and/or low-quality environmental conditions. To illustrate, when a user is in a low-lit environment and participating in a video stream, the image restoration system enhances the quality of the image by dynamically re-lighting the user's face. Moreover, it significantly enhances the image quality to the extent that other users viewing the video stream are unaware of the poor environmental conditions of the user. In addition, the image restoration system creates and utilizes an image restoration machine-learning model to improve the quality of low-quality images by re-lighting and restoring them in real time. Various implementations combine an autoencoder model with a distortion classifier model to create the image restoration machine-learning model.
