Image upscaling is a process that increases the resolution of an image, making it larger and clearer. This technique is often used in digital photography and graphic design to enhance the quality of images without losing important details. By adding more pixels, upscaling can improve the visual appearance of images, especially when displayed on larger screens. There are various methods for image upscaling, including traditional interpolation techniques and advanced algorithms like those used in machine learning. These methods analyze the existing pixels and predict new ones, allowing for smoother edges and better detail retention. This technology is widely used in applications ranging from video games to medical imaging.
