Abstract EN
Transmission estimation is a critical step in single-image dehazing.
The estimate of each pixel describes the portion of the scene radiance that is degraded by hazing and finally reaches the image sensor.
Transmission estimation is an underconstrained problem, and, thus, various assumptions, priors, and models are employed to make it solvable.
However, most of the previous methods did not consider the different assumptions simultaneously, which, therefore, did not correctly reflect the previous assumptions in the final result.
This paper focuses on this problem and proposes a method using an energy function that clearly defines the optimal transmission map and combines the assumptions from three aspects: fidelity, smoothness, and occlusion handling, simultaneously.
Fidelity is measured by a novel principle derived from the dark channel prior, smoothness is described by the assumption of piecewise smoothening, and occlusion handling is achieved based on a new proposed feature.
The transmissions are estimated by searching for the optimal solution of the function that can retain all the employed assumptions simultaneously.
The proposed method is evaluated on the synthetic images of two datasets and various natural images.
The results show that there is remarkable fidelity and smoothness in the transmission and that a good performance is exhibited for haze removal.
