Ma algorithms apamwamba kwambiri opangira ma siginecha opangidwa makamaka pamizere ya ICONYX ndi mawonekedwe owoneka bwino a BeamWare amathandizira ntchito ya wogwiritsa ntchito, chifukwa chake angagwiritsidwe ntchito mosiyanasiyana m'malo ambiri.

Kukambitsirana

Nkhaniyi yaperekedwa pakuwunika mwatsatanetsatane zokuzira mawu komanso kutengera mawu okhala ndi mabwalo apamwamba a DSP. Ndikoyenera kutsindika kuti chiphunzitso cha zochitika zakuthupi zomwe zimagwiritsa ntchito zokuzira mawu zachikhalidwe komanso zama digito zidafotokozedwa kale m'ma 50s. Pokhapokha pogwiritsira ntchito zipangizo zamagetsi zotsika mtengo komanso zabwino kwambiri ndizotheka kulamulira bwino machitidwe a thupi pokonza zizindikiro zamayimbidwe. Chidziwitsochi chimapezeka nthawi zambiri, koma timakumanabe ndipo tidzakumana ndi zochitika zomwe kusamvetsetsana kwa zochitika zakuthupi kumabweretsa zolakwika pafupipafupi pakukonzekera ndi malo a zokuzira mawu, chitsanzo chingakhale msonkhano wokhazikika wokhazikika wa zokuzira mawu (pazifukwa zokongola).

Zoonadi, zochita zamtundu uwu zimagwiritsidwanso ntchito mosamala, ndipo chitsanzo chochititsa chidwi cha izi ndikuyika mizati yopingasa ndi oyankhula akulozera pansi pamapulatifomu a sitima zapamtunda. Pogwiritsira ntchito zokuzira mawu motere, tikhoza kuyandikira ku zotsatira za "shower", kumene, kupyola pamtundu woterewu (malo obalalika ndi nyumba ya chipilala), phokoso la phokoso limatsika kwambiri. Mwanjira imeneyi, kuchuluka kwa mawu owonetseredwa kumatha kuchepetsedwa, ndikupangitsa kuwongolera bwino kwamawu.

Munthawi imeneyo yamagetsi otukuka kwambiri, timakumana ndi mayankho ochulukirapo nthawi zambiri, omwe, komabe, amagwiritsa ntchito fiziki yomwe idapezeka ndikufotokozedwa kalekale. Phokoso lachitsanzo cha digito limatipatsa mwayi wodabwitsa wosinthira zipinda zovuta kwambiri.

Opanga akulengeza kale zakuchita bwino pakuwongolera ndi kuwongolera mawu, chimodzi mwazomveka zotere ndikuwoneka kwa zokuzira mawu zatsopano (modular IC2 ndi Renkus-Heinz), zomwe zitha kuphatikizidwa mwanjira iliyonse kuti mupeze gwero lamawu apamwamba kwambiri, yoyendetsedwa mokwanira pokhala gwero la mzere ndi mfundo.
