PIFu

Pixel-aligned Implicit Function (PIFu) is a method used for 3D reconstruction from 2D images. It focuses on reconstructing the 3D geometry and texture of clothed humans while preserving the details present in the images, offering a memory-efficient and spatially aligned 3D representation for 3D surfaces. PIFu is particularly beneficial for researchers and developers in the fields of computer vision and graphics who require detailed and accurate 3D models from 2D inputs.
