In this work, a new hole patching method (namely as, HPDE) is proposed to repair the
damaged or ill-scanned three dimensional objects in real engineering applications. Our
method differentiates from other related algorithms mainly on the following three aspects.
Firstly, our algorithm sufficiently utilizes the point information around the considered hole for
each prediction by constructing point correspondences on both sides of the boundary curve
of the hole; secondly, the missing points in the hole region are predicted by the algorithm of …
