  We propose a combined reconstruction-classification method for simultaneously
recovering absorption and scattering in turbid media from images of absorbed
optical energy. This method exploits knowledge that optical parameters are
determined by a limited number of classes to iteratively improve their
estimate. Numerical experiments show that the proposed approach allows for
accurate recovery of absorption and scattering in 2 and 3 dimensions, and
delivers superior image quality with respect to traditional reconstruction-only
approaches.
