Grupa badaczy z kilku ameryka\u0144skich uniwersytet\u00f3w opublikowa\u0142a projekt PIFu<\/a><\/noindex> (Pixel-Aligned Implicit Function), kt\u00f3ry pozwala na zastosowanie metod uczenia maszynowego do tworzenia modelu 3D cz\u0142owieka na podstawie jednego lub kilku dwuwymiarowych obraz\u00f3w. System pozwala na rekonstrukcj\u0119 skomplikowanych wariant\u00f3w odzie\u017cy, takich jak sp\u00f3dnice z fa\u0142dami i szpilki, oraz r\u00f3\u017cnych fryzur, samodzielnie przywracaj\u0105c tekstur\u0119 i kszta\u0142t w obszarach niewidocznych na projekcji, na podstawie kt\u00f3rej tworzony jest model 3D.

Jako \u017ar\u00f3d\u0142o do rekonstrukcji obj\u0119to\u015bci makiety wykorzystywana jest sie\u0107 neuronowa, kt\u00f3ra pozwala na wyb\u00f3r najbardziej prawdopodobnego kszta\u0142tu i dedukcj\u0119 ukrytych element\u00f3w, bazuj\u0105c na modelu wyuczonym na r\u00f3\u017cnych wariantach istniej\u0105cych obiekt\u00f3w.
