entire spectrum can be varied, although not necessarily in the same way

for the entire image plane, rather than selecting only a single wavelength

band. In order to produce a multi-channel image, this optical setup is of-

ten combined with compressed sensing approaches [Mohan et al. 08, Kim

et al. 12].

1.6 Geometric Calibration

Applications such as 3D geometry reconstruction, view interpolation, and

so on require understanding the mapping between 3D real scene points

and image coordinates. The process of determining the actual value of the

parameters that control that mapping is called geometric camera calibra-

tion. In this section, a common model for this mapping is presented, and

the basic principles of lens distortion, ...
