Abstract

Ljudski mozak lako prepoznaje izmaglicu na slikama bez dodatnih informacija, međutim računalu su one nužno potrebne. Ovaj rad se bavi opisom i implementacijom dvaju algoritama koji zasnivaju svoje pretpostavke na parametrima na fotografijama na koje izmaglica ima utjecaj. Pretpostavka tamnim kanalom se zasniva na tamnim pikselima, a pretpostavka prigušenjem boja na zasićenju i intenzitetu svjetlosti piksela. Opisani su matematički modeli iza algoritama i međusobno uspoređeni njihovi rezultati.

Abstract (english)

The human brain easily recognizes the haze in the images without any additional information, however it's necessary for computation. This paper deals with the description and implementation of two algorithms that base their assumptions on parameters in photographs that are affected by haze. Dark channel prior is based on dark pixels while color attenuation prior is based on difference between saturation and brightness. Mathematical models behind algorithms.are described and their results are compared.
