From Wikipedia, the free encyclopedia

Computational imaging refers to any image formation method that involves a digital computer. Computational photography is a recently invented phrase referring to computational imaging techniques that enhance or extend the capabilities of digital photography. Within this rapidly evolving area, one can identify a number of broad research directions. These are given below, with a list of techniques in each area. For each technique, one or two representative papers or books are cited.

Computational illumination

[edit]

Controlling photographic illumination in a structured fashion, then processing the captured images, to create new images.

Computational sensors

[edit]

Detectors that combine sensing and processing, typically in hardware.


Note: The foregoing taxonomy was originally proposed by Shree Nayar. Deliberately omitted from the taxonomy are image processing (see also digital image processing) techniques that are applied to conventionally captured images in order to produce better images. Examples of such techniques are image scaling, dynamic range compression (i.e. tone mapping), color management, image completion (a.k.a. inpainting or hole filling), image compression. digital watermarking, and artistic image effects. Also omitted are techniques that produce range data, volume data, 3D models, 4D light fields, 4D, 6D, or 8D BRDFs, or other high-dimensional image-based representations.
