Image Noisy Elimination Using Advanced Linear Function

Abstract

Weather degradation such as haze, fog, mist, etc. severely reduces the effective range of visual surveillance. This degradation is a spatially varying phenomena, which makes this problem non trivial. Dehazing is an essential pre-processing stage in applications such as long-range imaging, border security, intelligent transportation system, etc. However, these applications require low latency of the pre-processing block. The proposed method can recover a high-quality haze-free image based on the physical model, and the complexity of the proposed method is only a linear function of the number of input image pixels. Experimental results demonstrate that the proposed method can allow a very fast implementation and achieve better restoration for visibility and color fidelity compared to some state-of-the-art methods
