In global warping, i got this error:

warping_resize: /usr/include/eigen3/Eigen/src/Core/DenseBase.h:261: void Eigen::DenseBase::resize(Eigen::Index, Eigen::Index) [with Derived = Eigen::Block<Eigen::Matrix<double, -1, -1>, -1, -1, true>; Eigen::Index = long int]: Assertion `rows == this->rows() && cols == this->cols() && "DenseBase::resize() does not actually allow to resize."' failed.

I found that it happened when executing SMatrixd V = solver->solve(b);

The following is part of codes in global_wraping.hpp

for (int it = 0; it < option.nums_iteration; it++) {
	auto K_copy = SMatrixd(K); // a deep copy
	const int K_row_offset = K_cols; // Shape Matrix is K_cols x K_cols
	line_optimizer.make_block_diag(K_copy, option.lambda_l, K_row_offset, 0);
	auto K_weighted = SMatrixd(K_copy * Q);

	SMatrixd A = eigen_row_concat(B_coeffs, K_weighted);

	this->solve_mesh(A, b_term);

	// opt_mesh.show_mesh(src, "mesh - it = " + std::to_string(it));

	// fix V, update theta
	line_optimizer.update_line_theta(opt_mesh);

	std::cout << "iteration " << it << " - ok" << std::endl;
	}
}

You use the Q matrix so that the whole mesh V_q can be multiplied by K*Q . But the optimization problem is to find the V_q which can minimize the energy E. Did you forget to compute the derivative of V_q? You need to compute the derivative and set it to 0 and then you can find the V_q to minimize the energy E. Er... Maybe I miss some codes or you made a mistake?
Look forward to your reply!!!Thx!

if (from.x == to.x) { // vert
if (from.x <= to.x) {
delta = Point(0, 1);
} else {
delta = Point(0, -1);
}
}

Dose from.x <= to.x should be from.y <= to.y ?

When I test your code with other images, if the parameter lambda_l = 100, I will get a bad result image.But if I ignored the line preservation and set lambda_l = 0, the result will be better. Do you face the same situation? Is something wrong in line preservation?

May I ask what's the meaning about Matrix Q? What the meaning of the shape-line weight corresponds to is in the paper？ Thank you！
Looking forward to your answer, thank you!
