Dependency library

Eigen is a C++ library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

Method

The core method for the blending process comes from Poisson Image Editing, in which the formula of computing vector b is as follow:

b[i] = div ( G( Source(x,y) ) ) - Neighbor(target i) ;  // i=1..N
