Upscaling algorithms

Upscaling algorithms are methods used to enhance the resolution of images or videos, making them appear sharper and more detailed on larger screens. They work by analyzing the existing pixels and predicting additional information to fill in gaps, effectively "guessing" what details should be added. Different algorithms use various techniques—some focus on maintaining natural appearance, while others prioritize sharpness or reducing artifacts. These algorithms are essential in modern displays, streaming, and imaging, allowing lower-resolution content to look better on high-resolution screens without needing to recreate original data from scratch.
