Detailed Description

template<class TInput, class TOutput>
class otb::Functor::MuellerToPolarisationDegreeAndPowerFunctor< TInput, TOutput >

Evaluate the min and max polarisation degree and min and max power from the Mueller image.

The order of the channels of the input image corresponds to : $\begin{pmatrix} {channel #0 }&{channel #1 }&{channel #2 }&{channel #3 } \\ {channel #4 }&{channel #5 }&{channel #6 }&{channel #7 } \\ {channel #8 }&{channel #9 }&{channel #10}&{channel #11} \\ {channel #12}&{channel #13}&{channel #14}&{channel #15} \\ \end{pmatrix}$

The class process step by step while $\tau <= 45$ and for each $\tau$ , while $\psi <= 90$ :

Define the incident Stokes vector:

$Si_{0} = 1$
$Si_{1} = \cos{\psi * \frac{\pi}{90}} * \cos{\tau * \frac{\pi}{90}}$
$Si_{2} = \sin{\psi * \frac{\pi}{90}} * \cos{\tau * \frac{\pi}{90}}$
$Si_{3} = \sin{\tau * \frac{\pi}{90}}$

Evaluate the received Stokes vector :

Evaluate power and polarisation degree :

$P = \max{0, Sr_0}$
$DegP = \sqrt{Sr_{1}^{2} + Sr_{2}^{2} + Sr_{3}^{2}} / Sr_{0}$

Keep the smallest and the biggest power ( $P_{min}, P_{max}$ ) and polarisation degree ( $DegP_{min}, DegP_{max}$ ) ).

Output value are:

channel #0 : $P_{min}$
channel #1 : $P_{max}$
channel #2 : $DegP_{min}$
channel #3 : $DegP_{max}$
