Firstly , we directly use the motion vectors of macro - blocks defined in mpeg - i / ii compressing standards and filter the immobile macro - blocks . then , we build a skin color model in ycbcr color space using the convergent property of skin color , and we present the gaussian model skin recognition method and positive - negative look - up table method in details . and we analyze the texture of skin after wavelet transform and present a bayesian method based texture recognition method and a high texture filtering method 根据皮肤的运动性，首先直接利用mpeg -中的压缩标准中有关宏块运动预测的方法，提取宏块的运动矢量，将没有运动的宏块过滤掉；然后，利用皮肤颜色的聚合性，在ycbcr颜色空间建立了皮肤的颜色模型，并分别阐述了基于高斯分布模型的皮肤检测法和正反概率表方法；最后，通过对皮肤进行小波变换后的纹理进行统计后，发现有效的利用皮肤纹理特征，可以比较有效的过滤掉那些具有类似于皮肤颜色的背景，分别阐述了基于贝叶斯方法的纹理检测方法和高纹理过滤法。
To guarantee the stability of the frame in strong earthquake motion , and on the basis of analysis on the concept of “ capacity design ” in the above three countries seismic design provisions , it is advised that the moment amplification coefficients at the bottom sections of columns for the frame structures in some seismic intensity be increased to reduce the possibility of the frame column yielding . taking the above three countries seismic codes as reference , it is recommended that it be added details of seismic design by using diagonal shear reinforcement to safeguard beams against sliding shear failure , when the positive - negative shear forces are reverse and the ratio is high 为了保证在大震作用下框架结构的稳定性,借鉴国外规范“柱-梁承载力级差系数”的思想,本文提出了对部分抗震等级的框架结构的柱端抗弯能力增强系数应予以提高,以降低框架柱屈服的可能性;参照国外有关规范的发展,本文建议对于正、负剪力反向且比值较大的框架梁宜增加交叉斜筋,以防止沿垂直裂缝发生严重的剪切错动。
Function of three valve units is take signal from lead pressure point introduce the positive - negative pressure measuring container of transmitter , to realize on or off between lead pressure point and measuring container , and on off between positive and negative pressure container , also can use as differential pressure balance check zero and when remove transmitter as cut - off valve 三阀组的作用是从引压点将信号引入变送器的正负压测量容室,实现引压点与测量容室之间接通或断开，以及正负压测量容室之间接通或断开,亦可作为差压平衡检测零点用和卸变送器时作截止阀用。
