Nasir Baig, Muhammad Mohsin Riaz, Abdul Ghafoor, Adil Masood Siddiqui · IEEE Signal Processing Letters · 2016
In this letter, an improved single image dehazing technique based on quadtree decomposition and entropy-based weighted contextual regularization is proposed. The boundary constraints are computed adaptively using statistical properties of image. The proposed technique produces high-quality dehazed image with better colors and minimal blocking artifacts. Simulation results compared visually and quantitatively with state-of-the-art existing schemes show the significance of proposed technique.
