This paper describes a novel method of enhancing shallow ocean optical images or videos using a fast dark channel prior descattering method. Absorption, scattering and color distortion are three major distortion problems for underwater imaging. In this paper, we propose a novel shallow water imaging model to compensate for the attenuation discrepancy along the propagation path and an effective underwater...
In order to achieve accurate automatic recovery of fixed-wing UAV at the known landing site, an airborne aided landing navigation system based on machine vision is designed and realized, and the key algorithms of the system are investigated. First, according to the need of automatic landing, such as high precision, real-time and strong anti-interference ability, a scheme of vision-aided landing navigation...
