Extension of the CASToR framework dedicated to multi-class reconstruction of medical images and Fisher information matrix estimation for $3\gamma$ PET/Compton imaging from continuous photon detections.
Implementation of the branch-and-bound algorithm for sparse spectral unmixing. The version submitted to the [EUSIPCO 2025](https://www.eusipco2025.org/) conference is based on the [UNMIX](https://gitlab.com/mlatif/bbhs_ext_cpp) C++ prototype. Supplementary material can be found [here](https://gitlab.univ-nantes.fr/ls2n-sims/l0-sparse-unmix-eusipco-supplementary-materials).
A Monte Carlo simulator for multi-class sensitivity maps estimations, compatible with CASTOR, designed for XEMIS2.
