Dark channel prior has been used widely in single image haze removal because of its simple implementation and satisfactory performance. However, it often suffers from halo artifacts or noise amplification, over-dark and over-saturation looking in some images containing heavy fog or large sky patches where dark channel prior is not established. To resolve these problems, this paper proposes a ro...

Abstrtract : Haze formation is the combination of airlight and attenuation. Attenuation decreases the contrast and airlight increases the whiteness in the scene. Atmospheric conditions created by floting particles such as fog and haze, severely degrade image quality. Removing haze from a single image of a weather-degraded scene found to be a difficult task because the haze is dependent on the u...

In this paper, we propose a novel atmospheric model–based defogging method from single image, for the image degraded by scattering due to atmospheric particles. The main advantage of the proposed algorithm compared with previous techniques is that it can reduce the Halo and blocking effects physically. We estimate the transmission using local extrema principle and bilateral filter that a high q...

Images/videos of outdoor scenes are usually degraded by the turbid medium in the atmosphere. In this paper, a novel single image-based dehazing framework is proposed to remove haze effects from image/video, where we propose two novel image priors, called the pixel-based dark channel prior and the pixel-based bright channel prior. Based on the two priors with the haze imaging model, we propose t...

Images captured in foggy weather conditions often suffer from poor visibility, which will create a lot of impacts on the outdoor computer vision systems, such as video surveillance, intelligent transportation assistance system, remote sensing space cameras and so on. In this paper, we propose a new transmission estimated method to improve the visibility of single input image (with fog or haze),...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
