DDD: Density Distribution Determination (opens in new tab)

DDD: Density Distribution Determination Horn, Berthold K.P. This paper presents a solution to the problem of determining the distribution of an absorbing substance inside a non-opaque non-scattering body from images or ray samplings. It simultaneously solves the problem of determining the distribution of emitting substance in a transparent non-scattering medium. The relation to more common vision problems is discussed. This is largely a cleaned up version of a solution found sometime ago when...
