Haze Removal Based on Refined Transmission Map for Aerial Image Matching

Yogendra Rao Musunuri, Oh-Seol Kwon
2021 Applied Sciences  
The DCP was used to estimate the transmission map based on patch-based processing, which also results in image blurring.  ...  Therefore, the proposed algorithm estimates a refined transmission map that can reduce the block artifacts and improve the image clarity without explicit guided filters.  ...  Thus, a low score indicates good perceptual quality, and a high score indicates poor perceptual quality.  ...
