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...

A duststorm image has a reddish or yellowish color cast. Though and hazy are obtained using the same process, no distortion as it not been disturbed by particles, but owing to an imbalance in channel, which is sand particles. As result, degraded rare certain channels. Therefore, balance step needed enhance naturally. This study goes through two steps improve image. The first singular value deco...

In foggy environments, outdoor insulator detection is always with low visibility and unclear targets. Meanwhile, the scale of haze simulation datasets insufficient. Aiming to solve these problems, this paper proposes a novel Dark-Center algorithm, which joint learning framework based on image defogging target detection. Firstly, dark channel prior algorithm used calculate sky transmittance then...

We present results on the consistency of standard cold dark matter (CDM) models with both the COBE normalization and the data from the 4th channel of the 9-point South Pole scan. We find that CDM models are consistent with both experiments, a conclusion which is at odds with some other analyses. This is partly due to our careful treatment of the temperature autocorrelation function, but also de...

Remote sensing image dehazing is challenging because it is massively ill-posed and the haze is dependent on the unknown depth information. Haze removal based on dark channel prior is effective, and refining the transmission map with Gaussian filter will produce a god result. But need to improve the naturalness and sharpness and effectiveness of images and to remove fine haze . So Proposes new a...

A novel strategy is proposed to address block artifacts in a conventional dark channel prior (DCP). The DCP was used estimate the transmission map based on patch-based processing, which also results image blurring. To enhance degraded image, single-image dehazing technique restores blurred with refined hidden Markov random field. Therefore, algorithm estimates that can reduce and improve clarit...
