Physically-constrained block-term tensor decomposition for polarimetric image recovery

HIGHLIGHTS

• What: By representing Stokes vector as third-order tensor the authors propose new physicallyconstrained block-term tensor decomposition called Stokes-BTD. To this aim the authors implement two algorithms StokesBTD based constrained alternated optimization and highlight constraints related to Stokes vectors.

The authors implement BPG for Stokes-BTD following guidelines presented, including . . .
