polar coordinate
基本解释
- 极坐标；极座标；极坐标系统
英汉例句
- This guy, you have two different ways of getting its polar coordinate equation.
有两种办法,可以得出极坐标系下的方程。 - Say, polar coordinates. Let's say that I have a function but is defined in terms of the polar coordinate variables on theta.
比如说极坐标，有一个函数,是根据极坐标θ定义的。 - And because you integrate first over r, well, first of all you should remember the polar coordinate formulas, namely x equals r cosine theta and y equals r sine theta.
这样的话，我们就先对r积分，当然了，首先得要记住坐标转换的公式，也就是x=rcosθ，y=rsinθ

专业释义
- 极坐标
The polar coordinate and Fast Fourier Transform(FFT) method are introduced to determine the invariant features of the transformed matrix. The targets are classified and recognized by calculating the same correlation of the characteristic matrix and the template features matrix.
利用多特征融合方法，从原始图像中提取待识别目标实现维数压缩任务；引入极坐标变换和快速傅里叶变换相结合的方法，确定变换后的不变特征矩阵；通过计算不变特征矩阵和模板特征矩阵的相关性对目标进行分类识别。数学
