Forskning

Kiran Raja forsker på biometri, generativ KI, medisinsk bildebehandling og explainable maskinlæring for ulike anvendelser. Arebeidet hans fremmer sikre og pålitelige biometriske systemer gjennom explainable kvalitetsvurdering, deteksjon av morfeangrep og template- protection. Han utforsker generativ KI, inkludert GANer og diffusjonsmodeller, både for å forbedre medisinsk bildebehandling, som usupervised læring for endoskopidata og forbedring av data. Hans forskning tar også for seg sikkerhetsutfordringer som ansiktsmorfering og manipulasjonsangrepsdeteksjon, deepfake-deteksjon og adversarial angrep. Han bidrar aktivt til å fremme vitenskapelig kunnskap, utvikle praktiske løsninger og forme internasjonale standarder innen biometrisk teknologi.

Publikasjoner

Kiran Rajas forskning innen biometri fokuserer på å utvikle sikre, pålitelige og personvernbevarende gjenkjenningssystemer. Han har bidratt betydelig til iris-, periokulær- og ansiktsbiometri, med vekt på malbeskyttelse, kansellerbar biometri og mobil autentisering. Hans nyere arbeid inkluderer forbedring av deteksjon av morfeangrep, utvikling av robuste funksjonsrepresentasjoner og integrering av dyp læring med tradisjonelle biometriske metoder.

Innen medisinsk bildebehandling anvender han avanserte metoder innen datavisjon og generativ kunstig intelligens for å forbedre diagnostisk bildekvalitet og analyse. Arbeidet hans inkluderer fjerning av spekulære refleksjoner i endoskopiske bilder, bruk av GAN-basert superoppløsning for kapselendoskopi og utnyttelse av diffusjonsmodeller for å forbedre medisinsk bilderekonstruksjon. Disse metodene forbedrer visualiseringen for kliniske eksperter og støtter automatisert beslutningstaking, og bidrar dermed til økt pålitelighet i KI-drevne helseteknologier.

Forskningen hans introduserer metoder for piksellnivå kvalitetsvurdering av ansiktsbilder, som gjør det mulig for systemer å gi tolkbare tilbakemeldinger på gjenkjenningsytelse. Ved å integrere forklarbare kvalitetsmål i biometriske prosesser adresserer han gjennomsiktighet og tillit – kritiske faktorer for implementering av KI i sensitive domener som grensekontroll og digital etterforskning. Hans nyere arbeider innen explainability på tvers av ulike anvendelser av datasyn og maskinlæring har resultert i nye tilnærminger.
