direction field meaning in Chinese
方向场
Examples
- And a direction field graph of the original image was also drawn
由锲特征得到方向场图来描述整幅图像。 - To research the texture with these ways are a relative new subject . and it is novel to plot the fracture development with direction field . to express the texture with a clear way for material research has a significant meaning
针对同一类断口纹理的研究还相对比较新,方向场的运用使得表达更直观,纹理分析与材料综合分析是本文的创新之处。 - Using the multi - cloud model to fit the ha - spectra data of the april 27 , 1981 post flare loop , we obtained the spacial distributions of the four physical parameters in the space of the post flare loop : the line - of - sight velocity v the excitation temperature tex , the micro - turbulence velocity vt and the column number density of the hydrogen atoms at the second level along the line - of - sight direction fields n2
我们利用多云模型处理了1981年4月27日太阳西边缘耀斑后环的三个时段的h光谱扫描资料。通过对1000余条对称谱线和不对称谱线的计算，我们得到了该耀斑后环各个时段在空间上的视向速度场，激发温度场，视向上处于第二能态的氢原子柱密度场以及湍流速度场。 - First pre - process the face image and localize the eyes , then normalize the face image based on the location of eyes , and extract the face feather using the independent component analysis algorithm combined with the principal component analysis algorithm to reduce the face image dimension ; attempt a direct gray scale minutiae detection approach based on ridgeline following to extract fingerprint feather , it will overcome the shortcoming of traditional method which would bring in false feathers during the binarization and thinning , and make some improvement such as the fingerprint image enhancement , direction field , stop criteria of ending point
首先对人脸图像进行预处理、定位人眼位置,进而根据人眼位置进行人脸图像的几何归一化,对归一化后的人脸图像本文提出了ica与pca相结合的方法提取人脸图像的特征:首先,利用主元分析法( pca )对人脸图像数据进行降维,然后采用独立分量分析( ica )算法提取人脸整体特征,从而得到较准确的人脸特征。
