Upscaling is a research area in the field of computer graphics and image processing that involves increasing the resolution or quality of an image or video. This is often done by using algorithms to enhance the details and clarity of the image, making it appear higher resolution than it actually is. Upscaling is commonly used in applications such as video games, virtual reality, and digital photography to improve the visual quality of images and videos. Researchers in this area work on developing advanced algorithms and techniques to produce high-quality upscaled images and videos that are visually appealing and realistic.
