Jörgen Ahlberg

Jag är adjungerad universitetslektor och docent i Datorseendegruppen, där ordet ”adjungerad” antyder att jag bara är där lite då och då, helst när det serveras tårta eller liknande i fikarummet. Större delen av tiden tillbringar jag på företaget Termisk Systemteknik AB, där har den ambitiösa titeln Forskningschef, och på företaget Visage Technologies AB, där jag också är Forskningschef. Jag är även involverad i Scienvisic AB samt gör lite jobb åt argicam AB (på konsultbasis).

Min forskning handlar om diverse datorseenderelaterade algoritmer och mojänger, ofta men inte alltid med termiska bilder och/eller följning som nyckelord. Jag är bihandledare för tre doktorander, Amanda Berg, Nenad Markuš och Ivan Gogić, som gör det mesta av själva jobbet.
