Functions
arma::fmat	scyl::compute_greyscale (const arma::fcube &source, const arma::fvec &wave)
	compute_grayscale returns a single channel grey scale image from a given hyperspectral image cube, approximating the scene's visual appearance to a human eye. More...
float	scyl::linear_interp (const float wavelength, const int band)
	linear_interp looks up a wavelength for a band (R, G or B) in the scyl::CAMERA_SENSITIVITY table, returning the corresponding float value from the table, or otherwise interpolating one based on the wavelengths position between elements. More...
arma::fcube	scyl::compute_rgb (const arma::fcube &I, const arma::fvec &illuminant, const arma::fvec &wave)
	compute_rgb creates a pseudo-colour representation of a given hyperspectral image cube. More...
arma::fcube	scyl::reconstruct_I (const arma::fvec &illuminant, const arma::fmat &k, const arma::fmat &g, const arma::fcube &s, float k_factor)
	reconstruct_I() creates a synthetic version of I based on it's constituents illuminant, k, g, s and big_k. More...
arma::fcube	scyl::reconstruct_s (const arma::fvec &illuminant, const arma::fmat &k, const arma::fmat &g, const arma::fcube &I, float k_factor)
	reconstruct_s() creates a synthetic version of s based on it's constituents illuminant, k, g, I and k_factor. More...
arma::fcube	scyl::reconstruct_s_elements (const arma::fmat &elements, const arma::fcube &abundances, const arma::ucube &indexes)
arma::fvec	scyl::reconstruct_illuminant (const arma::fmat &k, const arma::fmat &g, const arma::fcube &I, const arma::fcube &s, float k_factor)
	reconstruct_illuminant() creates a synthetic version of the illuminant based on given image components I, s, k g and k_factor. More...
arma::fcube	scyl::colour_jet (const arma::fmat &in)
arma::fcube	scyl::resample_image (const arma::fcube &in_image, const arma::fvec &in_waves, const arma::fvec &in_waves_new)
	resample_image() is used to change the number of bands an image matrix has using NURBS. More...
