The paper proposes bright and dark channel priors dependent single image based dehazing in two color spaces. The hazy RGB is first converted into YCbCr space. Transmission maps are estimated using dark channel priors (DCPs) and airlight of intensity (in YCbCr) and RGB components computed using three window sizes. Bright channel priors (BCPs) and threshold values are also computed for YCbCr and RGB...Show More
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 qua...Show More
