Single Image Dehazing Algorithm Based on Modified Dark Channel Prior

Abstract: Single image dehazing algorithm based on Dark Channel Prior (DCP) is widely known. More and more image dehazing algorithms based on DCP have been proposed. However, we found that it is more effective to use DCP in the RAW images before the ISP pipeline. In addition, for the problem of DCP failure in the sky area, we propose an algorithm to segment the sky region and compensate the transmission. Extensive experimental results on both subjective and objective evaluation demonstrate that the performance of the mo… Show more

“…We prove the performance of our method through quantitative and qualitative experiments, comparing it with stateof-the-art methods including DCP [8], Meng [19], Non-Local [10], MSCNN [13], DehazeNet [11], AODNet [12], He [20], Ehsan [21], Zhou [22], and D4 [14]. For quantitative evaluation, we adopt the widely used PSNR and SSIM [23] evaluation metrics.…”

“…Deep neural networks effectively improve the prediction accuracy, while the extremely high requirements for data with effective labeling make its training costs rise. The real situation is variable, and there may be noise interference such as light, angle, and distortion [7,8]. As the number of parameters increases, the computing time also increases, which means more computing power is needed.…”
