It differs from the traditional techniques of image scaling, which use a single image to increase the resolution, keeping the sharp edges. In contrast, superresolution merges information from multiple images taken from the same scene to represent details that were not initially captured in the original images.

The process of capturing an image or video from a real-life scene requires the following steps:

  • Sampling: This is the transformation of the continuous system from the scene of an ideal discrete system without aliasing
  • Geometric transformation: This refers ...
