Digital Image Modification Categories

There are many ways to categorize the tampering based on various points of view. For instance, photo manipulation can be divided into the following categories based on its aim:

  • Deleting or hiding a region or an object in the image.
  • Adding new objects into the image. This occurs, for example, when two or more images are spliced together.
  • Misrepresenting the image information. This can be achieved, for example, by techniques such as resizing, rotating, noise adding, blurring, or sharpening.
