Content-aware image resizing based on random-carving with probability by Ying-chun GUO, Jun-teng HOU, Ming YU, Rui-li WANG

“…To improve the running speed of image resizing,a fast content-aware image resizing algorithm was proposed based on the threshold learning and random-carving with probability.Firstly the important map was calculated by combining the graph-based visual saliency map and gradient map.Then the image threshold value was obtained by radial basis function (RBF) neural network learning.And by the threshold,the original image was separated into the protected part and the unprotected part which was corresponding to the important part and the unimportant part of the original image individually.Finally,the two parts were allocated different resizing scales and the random-carving with probability was applied to them respectively.Experiments results show that the proposed algorithm has lower time cost comparing to the state-of-arts algorithms in MSRA image database,and has a better visual perception on image resizing.…”

A survey of efficient deep neural network by Rui MIN

“…Recently,deep neural network (DNN) has achieved great success in the field of AI such as computer vision and natural language processing.Thanks to a deeper and larger network structure,DNN’s performance is rapidly increasing.However,deeper and lager deep neural networks require huge computational and memory resources.In some resource-constrained scenarios,it is difficult to deploy large neural network models.How to design a lightweight and efficient deep neural network to accelerate its running speed on embedded devices is a great research hotspot for advancing deep neural network technology.The research methods and work of representative high-efficiency deep neural networks in recent years were reviewed and summarized,including parameter pruning,model quantification,knowledge distillation,network search and quantification.Also,vadvantages and disadvantages of different methods as well as applicable scenarios were analyzed,and the future development trend of efficient neural network design was forecasted.…”

Study on the Online Wear Condition Monitoring Method for Mining Reducer based on Wear Particle Feature by Wu Huling

“…Aiming at the online wear condition monitoring of a mining reducer for engineering applications,the relationship between wear debris features and wear status is studied.Firstly,ferrograph images are firstly captured by using an online wear debris image acquisition system.Secondly,the wear particle features are extracted by utilizing digital image processing technology,where the Otsu’s automatic thresholding method is employed to separate wear particles from the image background,and the debris features of relative concentration and the maximum width are extracted using a pixel scanning method.Finally,the wear status of a mining reducer is analyzed based on the statistical features of online wear debris.Additionally,the experiments are carried out and the results demonstrate that the proposed method is effective to monitor a running machine.This study also provides a new approach for automatic monitoring and intelligent maintenance of mining reducer.…”

Hybrid tabu search algorithm for excellent Boolean function by Weiqiong WANG, Haojie XU, Meng CUI, Qiong XIE

“…Boolean function in symmetric cryptographic algorithm must satisfy excellent cryptographic criteria to ensure the security of the algorithm.By combining the advantages of tabu search algorithm and hill climbing algorithm, a new heuristic generation algorithm called hybrid tabu search algorithm for excellent Boolean function was proposed.A large number of Boolean function with high nonlinearity, low autocorrelation, one-resilient, optimal algebraic degree, optimal algebraic immunity, optimal (suboptimal) resistance to fast algebraic attacks could be obtained quickly by applying the proposed algorithm.Simulation results demonstrate that the cryptographic properties of the Boolean function obtained by the proposed algorithm with strong search ability and fast running speed are better than the results of known optimization algorithm.Moreover, the algorithm also provides good Boolean function that cannot be obtained by using construction method.…”

FATIGU TEST AND PARAMETRIC STUDY OF CRACKED STEEL PLATES REPAIRED BY CFRP by WU XiZhi, CHENG JunSheng, YANG Yu, HUANG Yi

“…At the thin steel plates running a period,cracks may occur at the material or weld,and traditional repair methods aren’t suitable for cracks repair of the thin steel plates.But the method of drilling hole at the crack tip and pasting CFRP on the steel plates is a choice for crack repair.Firstly,through five groups of fatigue test,it analyzed the effect of the crack fatigue life of the hole joint CFRP reinforcement and the other methods.Then,based on the cohesive force theory,it established the finite element model of notch steel plate reinforced with CFRP.With the finite element model,it studied the repair parameters of the stiffness,length and width of CFRP.The results demonstrate that the remaining fatigue life of the hole joint CFRP reinforcement is better than drilling holes or pasting CFRP,and even more than the steel plate with no crack.So it is especially suitable for the thin-wall steel plate with short cracks.…”
