Preprocessing for Local Bianry Pattern based Face Recognition Ning Xing1, a, Lan Xian Gui2, b 1School of Information Engineering, East China Institute of Technology, Nanchang, 330013,China 2School of Mechanical and Electronic Engineering, East China University of Technology, Nanchang,330013, China aemail:xning@ecit.cn, b email:xglan@ecit.cn Keywords: face recognition; local binary pattern; Preprocessing Abstract.
It helps to reduce computational complexity but it is susceptible to posture, illumination, size, facial expression and other factors.
The face image is divided into many small parts, and LBP local characteristics and statistical properties of histogram are applied into FERET face database to achieve better recognition results.
Although the LBP operators have many advantages, there are also some shortcomings when they are used in face recognition, for the recognition rate will be affected by the illumination, facial expression, age, noise etc..

Fig.3 The plastic disformation zone and the stress distribution The stability of coal pillar not only depends on the coal pillar width and shape, also depends on the mechanical properties of coal.
The width of the x1 can be calculated by the following formula: Eq.1 m——Mining of coal seam thickness, 3.7m μ——Poisson's ratio, 0.450 A——Lateral pressure coefficient, A=μ/(1-μ)=0.802 φ——The internal friction Angle of coal, 32° K——Stress concentration factor, 2.1 K*——Stress concentration factor,1.6 γ——Coal volume force, 25kN/m3 H——Buried depth,600m C——Coal's cohesive force，2.718MPa p1——The resistance of the support for coal, 0 After calculation: x1=7.35m Similar to the width calculation of x1, calculated x0=1.84m And the premise condition of keeping the chain pillars’ stability is: after the removal of both sides of the plastic zone, the central can still maintain a certain coal pillar elastic nuclear of width, and the width of the elastic core should be greater than twice of the coal thickness.
Analysis diagram can be concluded that the width of the entity coal which not affected by the influence of the mined-out area and roadway excavation.

Even a fractured rubber bush affects the safety of the bogie.
Finally, a novel service lifetime estimation for oil-damper rubber bushes operating under different and repeated loads was proposed by normalizing the ratio of the degrading rate of the spring constant with fatigue cycle, assuming that the damage rate of the bush is analogous to the degrading rate of its spring constant, which is one of most important properties of the bush.
There is a particular aspect of the mechanical response in carbon black filled rubber in which the stress-strain curve depends on the maximum loading previously encountered.
The damage to the oil damper bush can be represented in terms of factors such as hardness, fracture strength, displacement, etc.
