Hi @Erkaman

Some structures from Eigen source are used.

typedef Eigen::SparseMatrix<double> SpMat;
typedef Eigen::Triplet<double> Triplet;
typedef Eigen::VectorXd Vec;

Eigen::SimplicialCholesky<SpMat> solver;
..
Vec solutionChannels[3];		
Vec b(numUnknowns);

How to free the memory used by Eigen entities ?

When loading images you apply gamma expension (correction) with following code:

But this is actually gamma compression. The correct way for gamma expansion would be

pow(buf[i + 0] / 255.0f, GAMMA),

Same issue is when saving the image, but opposite.
