Olyan fejlesztőt keresek, aki tud nekem olyan programot írni, ami egy meglévő adatbázisból képes arcot felismerni IP kamerán keresztül. Legyen képes egyidejűleg legalább 5-6 kamerát kezelni. Tudjon API-n keresztül csatlakozni adatbázisokhoz. Teljesen új forráskóddal kell rendelkeznie. Windows alapú programnak kell lennie.

Egy egyszerű utility programot kell készíteni, mely egy Video SDK-n keresztül csatlakozik egy video szerver alkalmazáshoz (ennek a kódja biztosított C# nyelven), és a beérkező képeket le lefuttatja egy pre-trained hálón (Yolo, SSD vagy hasonlók) és kimenti azokat a képeket JPG fájlba, melyeken megadott típusú objektum (pl. autó) található.

Ezen a linken lehet megnézni például a wesl3y nevű trader aktuális portfólióját: Tehát azt kérem a programtól, hogy küldj...

Az elképzelés: Egy modul, vagy plug-in, ami a kliens és Sharepoint szerver oldal közötti adatforgalmat tömöríti egy algoritmussal, így kevesebb sávszélességet igényelve. A magja a programnak C++, ami aztán egy C#/.NET alkalmazásba van bújtatva(az első sebesség, az utóbbi pedig komponensek közötti kompatibilitás miatt). Tehát a modul/plug-in, beáll a küldött adat elé, tömöríti azt, majd másik oldalon kicsomagolja. A projekt befejezettnek tekintett egy bug-mentes kezdeti verziónál, ami átmegy egy terheléses teszten
