T he key component of our pipeline is HairMVSNet, a differentiable neural ar chitecture which represents a spatial hair structure as a continuous 3D ha ir growing direction field implicitly. Specifically, given a 3D query poin t, we decide its occupancy (whether it is inside the hair volume) and dire ction from observed 2D structure features. With the query point’s pixel-al igned features from each input view, we utilize a view-aware transformer e ncoder to aggregate anisotropic structure features to an integrated repres entation, which is decoded to yield\n3D occupancy and direction at the que ry point. HairMVSNet effectively gathers multi-view hair structure feature s and preserves high-frequency details based on this implicit representati on. Guided by HairMVSNet, our hair-growing algorithm produces results fait hful to input multi-view images. We propose a novel image-guided multi-vie w strand deformation algorithm to enrich modeling details further. Extensi ve experiments show that the results by our sparse-view method are compara ble to those by state-of-the-art dense multi-view methods and significantl y better than those by single-view and sparse-view methods. In addition, o ur method is an\norder of magnitude faster than previous multi-view hair m odeling methods.\n\nRegistration Category: FULL ACCESS, ON-DEMAND ACCESS\n \nLanguage: ENGLISH\n\nFormat: IN-PERSON, ON-DEMAND URL:https://sa2022.siggraph.org/en/full-program/?id=papers_228&sess=sess15 8 END:VEVENT END:VCALENDAR
