This package includes:

  1. The code for Light Transport Model (LTM) recovery, both overdetermined and underdetermined. See 'LTM_Recovery/demo_LTM.m' for a demo. This work is described in [2].

  2. The code for 3D scene estimation with light blockage model and wall-mounted sensors. See 'BlockageModel/demo_Blockage.m' for a demo. This work is described in [1] and [3].

  3. The code for floor-plane occupancy mapping with light reflection model and ceiling-mounted sensors. See 'ReflectionModel/demo_Reflection.m' for a demo. This work is described in [1].
