Future mobile wireless communication networks will be featured as heterogeneity in order to enhance network performance and improve user experience. For better adaption challenges over its complexity vulnerability, cell outage detection technique, a promising intelligent part of self-organizing (SON), has drawn considerable attention deal with unexpected faults. Our work is devoted two-tier macro-pico network. Based on observation metrics time domain, we employ classification algorithm...
Heterogeneous networks (HetNets) can increase network capacity through complementing the macro-base-station with low-power nodes, in response to ongoing exponential growth data traffic demand. While, unprecedented challenges exist planning, optimization, and maintenance HetNets, especially activities such as cell outage detection mitigation are labor-intensive costly. One potential solution address these issues is introduce extensively attracted self-organizing (SON). This paper mainly...
Panoramic images captured by the fisheye lens cameras cover very wide field of view (FoV) ranging from 180° to 360°, but image quality is low compared that high-end such as DSLR or compact with APS-C full frame sensors. In this paper, we aim use deep neural network (DNN) based methods improve panoramic quality. Specifically, enhance 5K resolution (5376×2688) camera at same resolution, which good for applications requires limited resources, low-cost high We build a Panoramic-High-end dataset...
To improve the security performance of color images encrypted, a new image encryption algorithm based on DNA computation and Chen system is proposed. In proposed algorithm, chaotic sequences generated by are applied to permutation confusion phase encryption. And mean value pixel each component used as part initial conditions system, which makes that different original have secret keys. Besides, operations can break bit planes plaintext entirely. Simulation results show suitable for...
Recent 3D room layout recovery approaches mostly concentrate on Manhattan layouts, where the vertical walls are orthogonal with respect to each other, even though there many rooms non-Manhattan layouts in real world. This paper presents a method generalizing across and worlds. Without introducing additional supervision, we extend current methods by predicting an extra surface normal feature, which is further used for adaptive post-processing reconstruct of arbitrary shapes. Experimental...
Abstract The audible noise (AN) of HVDC transmission lines, as an external manifestation the corona discharge, intensifies with increase altitude. In high‐altitude area, AN has been a key factor in determining type conductors for lines. order to study characteristics current and lines at high‐altitude, we erected test line altitude 4300 m, carried out tests under different voltages. Through test, basic data were obtained. Based on curve, inception electric field strength conductor was...
We introduce PanoPoint, the joint feature point detection and description applied to nonlinear distortions multi-view geometry problems between 360° panoramas. Our fully convolutional model operates directly in panoramas computes pixel-level locations associated descriptors a single forward pass rather than performing image preprocessing (e.g. panorama Cubemap) followed by description. To train PanoPoint model, we propose PanoMotion, which simulates representation different viewpoints...
The audible noise (AN) of HVDC transmission line at high altitude area is the key factor to determine conductor type. However, research on AN unipolar lines relatively lacking present. In this paper, three DC test with an 1700 m – 4300 were used carry out tests under different surface electric field strengths, and influence A-weighted sound level spectral characteristics obtained. results show that, presents a nonlinear trend change. When strength larger, law more obvious. addition,...
