Computational photography
wikipedia:
Computational photography refers broadly to computational imaging techniques that enhance or extend the capabilities of digital photography.
The output of these techniques is an ordinary
photograph, but one that could not have been
taken by a traditional camera.
What is computational photography
• Convergence of image processing, computer vision, computer graphics and photography
• Digital photography:
– Simply mimics traditional sensors and recording by digital technology
– Involves only simple image processing
• Computational photography
– More elaborate image manipulation, more computation
– New types of media (panorama, 3D, etc.)
– Camera design that take computation into account
