MATLAB code for HSI-2-RGB transformation
% HSI_2_RGB was customized for the live mice data and may work better on in vivo tissue.
rgb = HSI_2_RGB(wavelengths, calibrated_hs_cube);
% HSI2RGB offers 2 versions of transformation for transmittance and reflectance, respectively
rgb = HSI2RGB(wavelengths, calibrated_hs_cube, option);
option = 't': transmittance (microscopic images)
option = 'r': reflectance (in vivio/ex vivo tissue images)
%------- Both transformations were synthesized using sin/cos functions. They can be customized to you data. -------
