Compute the LMS cones absorption

For each type of cones (L,M,S)

For each (x,y) pixel position

For each wavelength

$$cones abs\left(x,y\right) = \sum_{\lambda = 400}^{850} \left( RI\left(\lambda, x, y\right) \times SPF\left(cones, \lambda\right)\right)$$ (13)

$RI\left(\lambda, x, y\right)$ : Wavelength Retinal image,

$SPF\left(cones, \lambda \right)$ : Smith-Pokorny fundamentals
