Abstract

Dehazing technology has made great progress on a single image, but due to the high time complexity, it cannot meet the real-time requirements of HD video dehazing. Aiming at this problem, this paper proposed a dark channel prior dehazing algorithm based on hardware architecture optimization. It used the hardware-oriented dual-scale joint filtering method and threshold comparison method to simplify the computational complexity of transmittance and atmospheric light value. At the same time, it used the interframe dependency constraint to suppress the flicker noise in the video defogging. The experimental results show that the dehazing speed of the proposed algorithm reaches 148.2 Mpixel/s, which is about 55 times higher than that implemented by software programming, and the dehazing speed of full HD video at 1920×1080 resolution reaches 69 fps, meeting the real-time requirements and high dehazing quality.
