It has a magnitude as well as phase angle. It is a complex quantity.

感抗不但有幅值，而且有相角，它是一个复数量。

Each pixel on multispectral and hyperspectral imagery can also be regarded as one vector and the whole image is a convex cone formed by a number of nonnegative discrete vectors,so endmember selection is equivalent to search for the vertices of a convex cone.

遥感图像中的每个像元都可以看作一个多维向量，整幅影像看作由离散的非负向量构成的凸锥，通过寻找凸锥的角点来自动获取图像的端元。

Third,argument-polar radius curve of polar coordinate system whose pole is geometric gravity is formed,and maximum and minimum value points are searched.

然后以重心为极点，对边缘点极坐标化，形成幅角-极径曲线，在该曲线上寻找局部极大极小值点。

For example, copies a rectangular portion size is 6 inches x 9-inch image design in a picture format, 8.5 inches x 11 inches in the middle of the 印张, when it will be necessary to cut on the four sides are 印张 will be trimmed; but if the image placed in an angle (for example, on the upper-left corner), you just need to cut both ways, thereby saving a membership card after processing time and reduces business card printing and membership card production costs.

例如，将一幅尺寸为6英寸×9英寸的图像设计在一张幅面为8.5英寸×11英寸的印张中间，裁切时就需要对印张的四边都进行裁切；但如果将图像放置在某个角上，就只需要裁切两边即可，从而节约了会员卡制作后加工时间，也降低了制卡和会员卡制作成本。

The four edges of each isosceles trapezoid are detected and the vanishing point of the direction of parallel edges and four corner points are worked out.

给定k(k≥6)幅包含等腰梯形的图像，分别检测梯形的 4条边，计算梯形平行边方向上的消影点和 4个角点。

We expect it will benefit the industry field to break through the optical measuring limits at present by offering some new ideas. Optical measuring research based on moire interferometry has developed for several decades. The main idea of this research is to utilize the moire effect caused by two superimposed gratings of identical or similar spatial frequency. One is the reference grating and it is a virtual grating created by a computer program in this research; The other grating is the image of grating projected on the measured surface by the DLP projector, and this grating will distort because of the different sloped profile of the surface. To superimpose the program-created grating and the captured distorted grating will derive the so-called moire effect. This research combined the basic theory of optical interferometry and moire effect to project the different phases of the projected grating fringes by the phase-shifting method and compute the principal value of arguments between -π,π. In the end, the phase unwrapping program based on discrete Fourier transform of solving PDEs is used to unwrap the phase of the measured surface, and finally the surface profile is derived by the optical measuring system.

以叠纹干涉术为基础的光学检测研究之发展早已行之有年，而在本研究中所采用的投影叠纹法(Projection moiré)之主要精神在於藉由两道空间频率相近或相同的光栅相互叠加而成的效应，其中一道为参考光栅，而本研究中的参考光栅是以程式产生可调整不同空间频率的虚拟光栅；另一道则为投影至待测物表面的光栅影像，而在起伏高度不一的待测表面上的光栅影像会受到待测物表面起伏状况不同而在观测方向产生光栅投影条纹影像的歪曲变形，将电脑产生的参考光栅与由影像撷取装置所获取投影於待测物表面的光栅影像作叠合，便会产生所谓的叠纹效应；利用基本的光学干涉理论与叠纹效应结合，本研究中以相移法来改变投影於待测表面的光栅相位，再以相移法的理论反运算出在带有待测面各点高度资讯之介於-π，π相位主幅角，再以离散傅立叶转换解偏微分方程的相位重建程式还原待测面的相位值，以得知待测面之表面轮廓。
