Computational Photography Epsilon Photography Low-level Vision: Pixels Multiphotos by bracketing (HDR, panorama) ‘Ultimate camera’ Coded Photography Mid-Level Cues: Regions, Edges, Motion, Direct/global Single/few snapshot Reversible encoding of data Additional sensors/optics/illum Essence Photography Not mimic human eye Beyond single view/illum ‘New artform’ Stereo-pair is a simple example of coded photography. Many decomposition problems, direct/global, diffuse/specular,

Special Aperture ‘Single Pixel’ Camera Larval Trematode Worm Shielded by screening pigment. The visual organ provides no spatial information, but by comparing the signal from 2 organs or by moving the body, the worm can navigate towards brighter or darker places. It can also keep certain body orientation. Despite lack of spatial vision, this is an evolutionary forerunner to real eyes. ‘Single Pixel’ Camera Larval Trematode Worm
