Anyone who knows how to convert from RGB to HSD color model?

Hello,

I'm working on my final bachelor project and it's about processing medical images. Right now, I need to convert an image from RGB to HSD color model. If you don't know that, HSD is a color model very useful in medical images. HSD means Hue-Saturation-Density. The channels Hue and Saturation can be implemented from the HSV or HSI color model. However, I have had many problems in implementing the code for the Density channel. I would be very grateful if someone could help me with that, because I really need to obtain the HSD color model for continuing working on the project.

Thank you all very much,

I hope to hearing from you soon,

Best regards,

Eva.

There is some information out there if someone feels like rolling a MATLAB implementation:

although I don't see that anyone has done so yet. It appears that it would require some modeling of the optical system to have knowledge of the absorbtion coefficients and the baseline intensity, so I don't know how useful the transform would be to someone who doesn't have that information.
