What is Instant-NGP Hash Encoding?
Instant-NGP mooy pexem NVIDIA biy tàggat Neural Radiance Fields ak yeneen graphique neural yu njëkk ci ay segond, du ay waxtu, ci denc man-mani yuñ mëna jàng ci benn tablo hash bu bari dayo. Dafa am solo ndax dafa defar seen 3D yu baax te gaaw ba melni dañuy weccoo xalaat.
Lan mooy jafe-jafe bi gëna mag ci NeRFs yu yàgg yi Instant-NGP di wut?
NeRFs yu yàgg yaa ngi wéeru ci MLP bu mag bu ñuy faral di laaj; Instant-NGP dafay wàññi li ñuy liggéey ngir gaawlu tàggat ak joxe.
Fan la Instant-NGP di denc li gëna bari ci paramet yiñ mëna jàng?
Man-mani yiñ mëna jàng ñu ngi dundu ci tablo hash yu bari resolusioŋ, bàyyi benn MLP bu ndaw ngir boole man-mani yiñ seet.
naka lañuy boolee man-man yi ci dayo resolusioŋ yu bari yi?
Niveau bu nekk dañu koy interpoler trilineaire ba noppi boole ko balaa ñu koy jox MLP bu ndaw bi.
naka lay def ba Instant-NGP di jëflante ak mbëkkante hash yi ci ay tabloom yu am dayo bu baax?
Mbëkkante mën nañu ko; gox yu am densité bu rëy dañuy defar ay gradient yu gëna am doole, suko defee MLP bu ndaw bi ak optimisation jàng ni ñuy saafaraa ay barab yuñ bokk.
Lu tollu ci ñaata la Instant-NGP di gaawal tàggat NeRF?
Soo toxalee représentation bi ci ay table hash ak wàññi MLP, tàggat bi jël ay waxtu mën na jeex ci ay seconde.
