Me Pēhea te Mahi ana o ngā Kaiwhakaputa Tā Moko AI: Te Whakamārama

He tauira whakahorohoro iti (diffusion model) kua akona ki ngā ataahua moko kiri te kaiwhakaputa moko kiri AI. Ka pānui ia i tō kupu tono, ka ahu ai i tētahi papa korotangi mā ngā hīkoi maha, ā, ka tū ki tētahi toi hou e hāngai ana ki ngā tikanga i ako ai ia i roto i tōna whakangungu.

He aha te hanganga tauira e tika ana mō tētahi kaiwhakaputa moko kiri AI?

Ko te nuinga o ngā kaiwhakaputa moko kiri e whakahaere ana i tētahi tauira whakahorohoro iti kua akona ki ngā toi moko. Ka huri tētahi kaituhituhi kuputuhi i tō kupu tono ki ngā āhua, ka mahi te U-Net ki te ahu i tētahi ata iti mā ngā hīkoi maha, ā, ka huri tētahi kaiuruuru i te iti whakamutunga ki tētahi hoahoa e kitea ana.

Ko te hanganga e rangona whānuitia ana ināianei ko te whakahorohoro iti — taua whānau anō e tū ana ko Stable Diffusion, ko SDXL, ko ngā whakaputanga hou o Midjourney, me te nuinga o ngā peka moko-ake e tuwhera ana. Ko te kupu 'iti' te matua: ko te tauira e mahi ana i roto i tētahi āhua i kūkūhia ai, e ono tekau mā whā nei o te rahi, nō reira ka mutu te whakaputanga i roto i ngā hēkona kaua ko ngā miniti.

E toru ngā wāhanga e tino tino ana. Ka huri tētahi kaituhituhi kuputuhi (he ahu CLIP, T5 rānei) i tō kupu tono tuhituhi ki tētahi huinga āhua e mau ana i te tikanga, kaua ko ngā kupu anake. Ka mahi te U-Net ki te ahu o te tūmahi, i ia hīkoi i ia hīkoi ka ahu ia e tōia ana e taua huinga āhua — nō reira ka ahu tonu te tauira ki 'ngā mea e rite ana ki te kupu tono.' Ka whakaaro tonu tētahi kaiuruuru autōmata ki te whakawhānui i te iti whakamutunga ki tētahi ata e kitea ana.

Ko te wāhanga ake mō ngā moko ka puta ake i te wā o te whakangungutanga. Ka akona tētahi tauira tūāhanga kua kite i te ipurangi whānui ki tētahi kohinga moko — ngā pepa toi, ngā ata i mahia, ngā āhua raina, ngā tauira — tae noa ki ngā taumaha o te whatunga e ahu ana ki ngā tikanga ataata o ngā moko: ngā raina kaha, ngā wāhi haunga, ngā tohu, ngā tikanga o te fine-line me te traditional. Ka tāpiri ētahi hua i runga i ngā LoRAs (ngā kaiwhakarite iti mō ia āhua). Ko te hua mōu ko tā te taputapu e mōhio ana ki te tikanga o 'single needle' me 'American traditional' i mua ake i tō tuhi mai. Mēnā e hiahia ana koe ki te whakataurite i ngā taputapu AI moko ināianei, ko te hanganga he ahu pērā tonu — ko ngā rereketanga kei roto i ngā raraunga whakangungutanga me ngā tāutanga whakaputanga.

Me pēhea te huri o te taputapu i tō kupu tono tuhituhi ki tētahi hoahoa moko?

Ka tohua, ka tōpūtia tō kupu tono ki tētahi āhua, ā, ka tukuna ki te U-Net hei āhuatanga i ia hīkoi ahu. Ka tīmata te tauira i te koreinga o korotangi, ā, ka tangohia e ia ngā wāhanga e kore ana e hāngai ki te āhua kupu tono, ka toe mai he ata e hāngai ana.

Ko te huri i ngā kupu ki ngā ata ehara i te kimi. Kāore te tauira e rapu ana i tētahi papakupu o ngā moko e hāngai ana ki tō kupu tono — ka whakaputahia he ata kāore anō i reira, ā, ka ārahi ana e ngā āhuatanga ohaoha i kapoihia i te wā whakangungutanga. Ko tēnei rereketanga he mea nui nā te mea ka whakamārama i ngā kaha (te āhua hou, ngā rerekētanga maha) me ngā ngoikoretanga (ngā hapa tūāhua i ētahi wā, te nekeneke o te kupu tono).

I roto i ngā mahi, ka haere te kupu tono mā tētahi kaitohu ka wawahi i a ia ki ngā wāhanga iti-kupu, ā, mā te kaituhituhi kuputuhi, ka whakaputahia he raupapa o ngā āhua e mau ana i te tikanga. Ka noho ngā āhua ki tētahi wāhi e tata ana tō 'kōtuku' ki ērā atu manu, ko 'fine-line' ka noho tata ki ērā atu āhua iti, ā, ko 'negative space' e tō ana ki ngā hanganga e māmā ana. Ka tangohia ngā āhuatanga e te U-Net, ā, i ia hīkoi ahu ka whakatauhia e ia ngā āhuatanga korotangi e pupuri ana, e tango ana hoki.

Ko te ārahi kore-arotahi te hurihanga e whakahaere ana i te māmā o te whakaaro o te tauira ki a koe. Ko te ārahi iti ka whakaputahia ngā hua māmā, auaha hoki ake; ko te ārahi teitei ka pēhia te pūmau ki te kupu tono — ko ētahi wā ka ngaro te kounga o te ata. Ka kīia ana ngā hīkoi tauira (kotahi tekau ki rima tekau) ko te rahi o te whakaaro me te āhua. Ko te kākano — he ira kotahi — ka tohu i te papa korotangi tīmata; ko te kupu tono me te kākano kotahi ka whakaputahia tōtika te ata kotahi, ko tērā tē āhua i te wāhi o te tūāpapatanga. Ka mutu te whakaputanga, ka taea e koe te mātakitaki i tētahi moko i whakaputahia ki runga i tō kiri ka mutu te huri i tētahi hoahoa i whakaputahia ki tētahi tauira hei kawe ki tō kaitoi.

He aha te mahi a tētahi tāurutanga ata i roto i te whakaputanga e mōhio ana ki te kiri?

Ka taea e tētahi tāurutanga ata te āhua o tō kikokiko tonu. Ka tōpūtia te ata me te kupu tono, nō reira ka whakaaro te whakaputanga ki ngā oripārore, te rahi, me te wāhi noho o te wāhanga tinana — kaua ko te whakaputahia he hoahoa māmā ka taea ana te tāpiri ki te kiri.

Ko te whakaputahia kuputuhi-ki-ata anake ka whakaputahia he hoahoa e tū ana i runga i tētahi papa mā. He pai tera mō te whiriwhiri i ngā mea e hiahia ana koe, engari ka wareware i te here kotahi nui rawa atu o tētahi moko moni: ko te tinana e noho ana. He ōpiri te kiri, he kōkiri, he toru-āwhio. Ko tētahi hanganga e ōrite ana i te āhua PNG tapatahi ka kitea he kōpeke ina takahi ana i te tinana o tētahi ringa, ka whai ai i te raina o tētahi ūpoko.

Ka kati ai te whakaputahia me te tāurutanga ata tēnei āputa. I muri i ngā arai, ka whakamahi te pūnaha i tētahi o ngā tikanga — ko ControlNet, ko IP-Adapter, ko te whakaaro hohonu, ko img2img rānei me te kaha ahu iti — ki te tāpiri i ngā kōrero mō tō ata ki roto i te ara whakahorohoro. Ka taea e te tauira te whakamārama i te āhua o tō ringa, i ngā wehenga hinengaro o tō tuarā, i te heke o tō taha ūpoko, ā, ka whakaritea te hoahoa i ruia ai. Ka whakaputahia he neke e takahi ana i tō huamoa; ka whakaputahia tētahi hoahoa i rite ana mō tō rūma ringa.

Ko te whakamahi tuarua o tētahi tāurutanga ata ko te whakamātauranga: kaua ko te āhua i te ara whakaputahia, ko te pūnaha e tāpiri ana i tētahi hoahoa mutunga ki tō ata me te whakatikatika āhua, te hāngai kapua, me ngā ataata. Ko tēnei te ara e kite ai koe i te āhua o te moko i mua i te rīpoata — ā, ko te ara tino māmā rawa atu ki te kite he hē tōu whakaaro i runga i te mata o tō hinengaro mō tō wāhi noho.

Ko hea ngā wāhi e heke tonu ana te whakaputahia moko AI i ngā kaitoitoi tangata?

He pai te AI mō te whakaaro, he ngoikore mō ngā mahi whakamutua. Ka tino ngoikore ia ki te hangarite pono, ngā kanohi, ngā ringa, ngā kuputuhi, me te whakaarotia o te nunga o tētahi hoahoa i roto i ngā tau — ngā mea katoa ka riria ana e tētahi kaitoitoi mōhio.

Ko te whakautu pono ko te AI he hoa whakaaro pai ake i te kaiwhakamutua. He wawe ake ia i tēhea tangata rānei ki te tūhura i ngā arahanga, ki te whakaputahia i ngā rerekētanga, ki te tūhura i ngā take e rau ana o te whakaaro kotahi. Ka huri katoa tērā i ngā wā tūāmua o te hoahoa moko. Engari ko te āputa i waenga i te 'ata pai i whakaputahia' me te 'moko pai' he mea tino, ā, ka puta ake i ngā wāhi motuhake.

Ko te hangarite te mea tuatahi. Ko ngā tauira whakahorohoro he tūāhua — kāore e whakamana ana i te tahi kanohi ki te rua e ōrite ana, ka ōrite ana ngā kāhui pua e rua, ka ōrite ana ngā wāhanga tekau mā rua o tētahi maṇdala. Ka tata koe ki tēnei me te kupu tono tika me te kākano tika, engari ka hia he tangata ki te horoi i te kōnae mēnā ko te hangarite te take o te āhua. Ko ngā kanohi, ngā ringa, me ngā kuputuhi iti te taunga hapa tuarua mō tēnei take anō: ko te iti tauiri nui i roto i ngā wāhi tikanga nui ko te wāhi e tino kino ana ai ngā tauira whakahorohoro.

Ko te ngoikoretanga hohonu ko te whakaaro. Kāore tētahi tauira whakahorohoro i mātakitakia he moko e ora ana. Kāore ia e mōhio ana ka poua iti ake ngā raina iti rawa atu o taha o tētahi maihao i roto i ngā tau e rua, ka ngaro te tae mā i te rā, ka ngaro katoa te hoahoa i topatia ki ngā sentimita e toru i te pikau o te hinu. Ko ērā ngā mea ka kīia e tētahi kaitoitoi tū ana. Whakamahi AI ki te whakaputahia, ki te arotahi, ki te whakamana i te āhua — ā, kawea tō kōnae ki tētahi tangata kua whakauru ngā haora e maha noa atu ki te mātakitakia i te pēhea o te hinu ki runga i ngā tinana, ka tukua rātou ki te wāhanga kore taea e te miihini.

Momo kaiwhakaputa mā te āhuatanga tāurutanga me te kounga putanga

tauira whakahorohoro — He whatunga koiora auaha ka akongia ki te huri i tētahi ara pēhi-hīkoi. Ka tīmata i te korotangi, ka tāmata ana e ia ki te kite me te tangohia o te korotangi — ā, ka ārahi ana e tētahi kupu tono tuhituhi, ata rānei — tae noa ki te puta mai o tētahi ata e aro ana.
