Do you have some old photos lying around that have seen better days, why not use software that uses AI (artificial intelligence) to make some improvements to those photos.
This is a free tool recently developed by Tencent researchers, GFP-GAN (Generative Facial Prior-Generative Adversarial Network), that can restore damaged and low-resolution portraits. The technology merges info from two AI models to fill in a photo’s missing details with realistic detail in a few seconds, all the while maintaining high accuracy and quality.
