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.
