Multi-NeuS: 3D Head Portraits from Single Image with Neural Implicit Functions. (arXiv:2209.04436v1 [cs.CV])

We present an approach for the reconstruction of textured 3D meshes of human
heads from one or few views. Since such few-shot reconstruction is
underconstrained, it requires prior knowledge which is hard to impose on
traditional 3D reconstruction algorithms. In this work, we rely on the recently
introduced 3D representation $\unicode{x2013}$ neural implicit functions
$\unicode{x2013}$ which, being based on neural networks, allows to naturally
learn priors about human heads from data, and is directly convertible to
textured mesh. Namely, we …
