1) Concentration in variation distance
铅直方向浓度
3) NTOP,night-time ozone profile
夜间臭氧垂直方向的分布 不同高度的臭氧浓度
5) histograms of oriented gradients(HOG)
方向梯度直方图
1.
For the coarse scale images,the histograms of oriented gradients(HOG) descriptor is used to perform a nearest neighbor image matching,which neglects the disturbance of local texture,and complements the deformable layer graph matching method in both scale and computing speed.
对粗尺度图像提出基于方向梯度直方图算子的图像匹配算法,利用物体的整体形状信息进行全局匹配,能忽略局部纹理的干扰,并具有运算速度快的优点,且与分层图匹配算法在计算尺度图像及速度上形成互补。
6) lead concentration
铅污染浓度
1.
Meteorological factors influencing lead pollution in the air in Gejiu are demonstrated,based on which,the variation rules of lead concentration in the air are pointed out for controlling lead pollution.
叙述了个旧市环境空气中影响铅污染浓度的气象因素,铅污染度的变化规律,为治理铅污染提供一些科学依据。
