QPoisson

Implement Poisson blending algorithm in a simple photo editor with Qt Frame on Windows.

Usage

Click to open dest img, then click to open src img
Click to circle an area on src img, then click to paste the circled area onto dst img
Click to blend the pasted area into dst img

git clone https://github.com/Genius-Society/QPoisson.git
cd QPoisson

Please refer to this blog post for this section.

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

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
