Abstract
Dehazing is an image restoration process to eliminate the hazy effect. Approximation of the transmission, which encodes the scene depth information, is the most significant step to tackle the dehazing problem. In this thesis, we propose a textured-region constraint to deal with inaccurate estimation on transmission within a textured region. The textured-region constraint assumes that transmission for pixels in a textured region should be similar. By including the textured-region constraint, the objective function guarantees to have a global optimal solution with constant textured-region transmission. Our experimental results show significant improvement in textured-region transmission and dehazed results.
