upscaling

Upscaling is the process of converting a digital image or video from a smaller size to a larger one, aiming to improve visual quality. Since increasing size involves adding more pixels, upscaling uses algorithms to predict and fill in missing details, making the image appear clearer and sharper on bigger screens. Modern upscaling techniques leverage artificial intelligence and machine learning to analyze patterns and generate more accurate details, resulting in a more natural and less pixelated appearance. Essentially, upscaling helps images look better on higher-resolution displays without requiring the original high-resolution file.
