WebResizing images for the web and email are perhaps the most common ways to share digital photos. Particularly for web presentation, being able to retain artifact-free sharpness in a downsized image is critical — yet may prove problematic. Unlike in photo enlargement where jagged edges are a problem, downsizing results in the opposite aliasing ... Downscaling is any procedure to infer high-resolution information from low-resolution variables. This technique is based on dynamical or statistical approaches commonly used in several disciplines, especially meteorology, climatology and remote sensing. The term downscaling usually refers to an increase in spatial resolution, but it is often also used for temporal resolution. This is not to be confused with image downscaling which is a process of reducing an image from a high…
