... mismatchin the environmental conditions. The inverse problem in this sense refers to the process of modeling the mismatch in the form of a transformation and resolving it via an inverse transformation. ... transformation. In this section, we introduce the method of modeling the mismatch as an affine transformation. Before getting into the details of the inverse problem i...
