Image Operations

Updated 24 Sep 2026

•
What it is
- •
  image transformations classified by the input information required to compute their output
•
Print operations
- •
  each output value depends on the corresponding input pixel
- •
  examples: fixed brightness mapping or fixed-threshold classification
•
Local operations
- •
  each output value depends on a neighborhood
- •
  examples: Median Filter, smoothing, and local edge operators
•
Global operations
- •
  output depends on information from the entire image
- •
  examples: an intensity mapping derived from the full image histogram or a transform of the complete image
•
Caution
- •
  a pixelwise final fomrula can still dpeend on globally estimated parameteres
