Abstract

Dolaskom HDR (eng. High Dynamic Range) slika, pojavio se problem u njihovom prikazivanju na standardnim zaslonima, koji koriste sustav boja koji ne podržava isti dinamički opseg. Kontrast se, pri sažimanju slika za prikaz, znatno povećava, što znatno oštećuje kvalitetu same fotografije. Kao odgovor na problem se pojavljuju različiti operatori preslikavanja intenziteta, kojima je cilj prilagoditi sliku za rad na standardnim monitorima, podešavajući intenzitet slike uz očuvanje njenih detalja.... More Ovaj rad detaljno proučava nekoliko takvih operatora – od ideja koje su dovele do njih do konkretnih postupaka njihovog primjenjivanja. Njihov utjecaj na boju se također raspravlja. Ukratko se opisuje i objektivno mjerilo kvalitete dobivene slike, TMQI. Naposlijetku, dvije od raspravljanih metoda su implementirane, i njihovi rezultati su prikazani u samom radu. Less

Abstract (english)

With the arrival of HDR (High Dynamic Range) images, there came a problem of displaying them on standard monitors, which happen to use a color system which use a significantly lower dynamic range. By attempting to display such images, the resulting compression makes the contrast too high. The solution to such a problem came in the form of tone-mapping operators. Their goal is to adapt the image for standard monitor display by adjusting the image intensity, while preserving its details. This... More work will go into more detail on a few of those operators – from their starting ideas, to their piplines. Their effects to image color are also discussed. An objective measure of quality for the resulting images, TMQI, is described. Finally, two of the discussed methods are implemented, and their results are shown in the paper itself. Less
