ู„ุฐุง ุฑุฃูŠุช ู‡ุฐุง ูˆุจุฏุฃุช ุจุงู„ุชุณุงุคู„ุŒ

can we create a model like this for anyone?

ูˆููŠ ุงู„ู†ู‡ุงูŠุฉ ุชูˆุตู„ุช ุฅู„ู‰ ุญู„ ุฌุฏูŠุฏ

that can build a model of a person using nothing but these:

03:01
It turns out this problem is very challenging,

ูˆู…ู† ู‡ู†ุงูƒุŒ ุจู…ู‚ุฏูˆุฑู†ุง ุจู†ุงุก ู†ู…ูˆุฐุฌ ู…ุชูˆุณู‘ุท

203326
1403
ุงู„ู…ุฐู‡ู„ ููŠ ู‡ุฐุง ุงู„ุฃู…ุฑ
03:24
is that the photo collection can come from your typical photos.

It doesn't really matter what expression you're making

ู„ุง ูŠู‡ู… ุญู‚ุงู‹ ู…ุง ุงู„ุชุนุจูŠุฑ ุงู„ุฐูŠ ุชุตู†ุนู‡

ุฃูˆ ุฃูŠู† ุงู„ุชู‚ุทุช ุชู„ูƒ ุงู„ุตูˆุฑ.

What matters is that there are a lot of them.

1736
ูˆู…ุงุฒู„ู†ุง ู†ูุชู‚ุฏ ู„ู„ุฃู„ูˆุงู† ู‡ู†ุงุŒ
03:36
so next, we develop a new blending technique

ู„ุฐู„ูƒ ุทูˆู‘ุฑู†ุง ุชู‚ู†ูŠุฉ ุฏู…ุฌ ุฌุฏูŠุฏุฉ

that improves upon a single averaging method

ูˆุชู†ุชุฌ ู‚ูˆุงู…ุงู‹ ูˆุฌู‡ูŠุงู‹ ูˆุฃู„ูˆุงู†ุงู‹ ุญุงุฏู‘ุฉ.

ูˆูŠู…ูƒู† ุงู„ู‚ูŠุงู… ุจุฐู„ูƒ ู„ุฃูŠ ุชุนุจูŠุฑ.
