Scale-space behavior of corners is important for developing an efficient corner detection algorithm. In this paper, we analyze the scale-space behavior with the Laplacian of Gaussian (LoG) operator on a planar curve which constructs Laplacian Scale Space (LSS). The analytical expression of a Laplacian Scale-Space map (LSS map) is obtained, demonstrating the Laplacian Scale-Space behavior of the planar curve corners, based on a newly defined unified corner model. With this formula, some Laplacian Scale-Space behavior is summarized. Although LSS demonstrates some similarities to Curvature Scale Space (CSS), there are still some differences. First, no new extreme points are generated in the LSS. Second, the behavior of different cases of a corner model is consistent and simple. This makes it easy to trace the corner in a scale space. At last, the behavior of LSS is verified in an experiment on a digital curve. © 2015 IEEE.

Online dress shopping is becoming an increasingly popular way of shopping and nowadays image-based dress retrieval plays an important role in identifying their favorite items for customers. In this paper, we present an efficient retrieval of dress image via improvement of deep learning. The deep learning is usually realized by convolutional neural networks (CNNs). We design the CNN by four sublayers followed by an output, which gives a retrieval of dress image. Further, we improve CNN by activation function to induce the sparsity in the hidden units. The deep network can be efficiently trained using the improvement. The results show that the matching results can be efficiently acquired, which proves the effectiveness of our method such as accuracy and computation complexity. © 2016 ICIC International.

During April 7–21 2020, KAGRA conducted its first scientific observation in conjunction with the GEO600 detector. The dominant noise sources during this run were found to be suspension control noise in the low-frequency range and acoustic noise in the mid-frequency range. In this study, we show that their contributions in the observational data can be reduced by a signal processing method called independent component analysis (ICA). The model of ICA is extended from that studied in the initial KAGRA data analysis to account for frequency dependence, while the linearity and stationarity of the coupling between the interferometer and the noise sources are still assumed. We identify optimal witness sensors in the application of ICA, leading to successful mitigation of these two dominant contributions. We also analyze the stability of the transfer functions for the entire two weeks of data to investigate the applicability of the proposed subtraction method in gravitational wave searches.

Under the condition of plaintext, by using the bit's statistical property of both English and Chinese words, a message extraction method for the sequential LSB (least significant bit) steganography in spatial domain was promoted and the extraction message accuracy was improved. Next a message extraction method for the random LSB steganography in spatial domain was put forward. Firstly, the unicity distance was obtained to recover the stego key;secondly, by stego key exhaustive searching, each stego key's steganographic path was determined and the LSB was extracted with the length of T;thirdly, a new subsequence was gained with the first bit of the LSB as the beginning and 7 sampling interval, and the true stego key could be determined if the subsequence was the sequence of all zeros or all non-zeros. Besides, the leak detection was also studied. The experimental results have proved the feasibility and effectiveness of the method. ©, 2015, Huazhong University of Science and Technology.

Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw value

Wireless Power Transfer has become a commercially viable technology to charge devices because of the convenience of no power wiring and the reliability of continuous power supply. This paper concerns the fundamental issue of wireless charger placement with electromagnetic radiation (EMR) safety. Although there are a few wireless charging schemes consider EMR safety, none of them addresses the charger placement issue. In this paper, we propose PESA, a wireless charger Placement scheme that guarantees EMR SAfety for every location on the plane. First, we discretize the whole charging area and formulate the problem into the Multidimensional 0/1 Knapsack (MDK) problem. Second, we propose a fast approximation algorithm to the MDK problem. Third, we optimize our scheme to improve speed by double partitioning the area. We prove that the output of our algorithm is better than (1 - ϵ) of the optimal solution to PESA with a smaller EMR threshold (1 - ϵ/2)Rt and a larger EMR coverage radius (1 + ϵ/2)D. We conducted both simulations and field experiments to evaluate the performance of our scheme. Our experimental results show that in terms of charging utility, our algorithm outperforms the prior art by up to 45.7%.

An SIMD Code Generation Technology for Indirect Array

An SIMD Code Generation Technology for Indirect Array

引用

2015 7th International Conference on Computer Research and Development (ICCRD 2015)

作者： Peng-yuan Li Rong-cai Zhao Qing-hua Zhang Lin Han State Key Laboratory of Mathematical Engineering and Advanced Computing

Due to disjoint memory references and non-aligned memory references, existing SIMD compilers can't vectorize loops containing indirect array utilizing SIMD(Single Instruction Multiple Data) instructions. However, addressing this problem is inevitable, since many important applications extensively use this program pattern to reduce memory and computation requirement. In this paper, we propose a new efficient code generation technique for indirect array. For an irregular indirect array access, we adopt two separately registers to store the array base and the index address. It significantly contributes to the performance improvement by vectorizing more loops and reducing the overheads. We also developed this method in our auto-vectorization compiler SW-VEC. The experimental results show that the proposed method can translate applications within direct array access into high-performance targeted vectorized codes, thereby advancing the execution efficiency adequately.
