An efficient volume repairing method by using a modified Allen-Cahn equation

作者：

Highlights：

• We repair the visualized volumes in respect to recover lost voxels and fill holes.

• Volume repairing can be addressed without increasing the dimensionality of the transfer function.

• Our algorithm is simple to implement and achieves fast convergence.

• Visualization quality of volumes can be significantly improved.
