比例变换 meaning in English
transformation of scale
Examples
- A scaling transformation only alters the size of an object
（比例变换仅改变一个物体的大小。 ） - The normal methods of translation , rotating and scaling can not be applied to the affine transform of fractal images
通常分形图不能用常规的平移、旋转和比例变换方法来进行仿射变换。 - Such operations include rotation , translation , scaling , reflecting , orthographic projection , and perspective projection are provided to control the location of geometric models
其中包括旋转变换、平移变换、比例变换、反射变换、正交投影变换和透视投影变换。利用这几种变换的组合建立取景体。 - In order to resolve parallel shift , rotation and scale shift of images , parallel shift can be resolved by fourier transform ; rotation can be resolved by polar transform ; scale shift can be resolved by ln transform
为了解决图像平移、旋转、比例变化对相关的影响，可通过傅里叶变换解决平移的问题；通过polar变换解决旋转的问题；通过ln变换解决图像比例变换的影响。 - 2 . the radiant characteristics of the sar images are evaluated , which includes relative calibrations and absolute calibrations of the sar images , corrections of the antenna patterns , and ratio transforms and contrast adjustments of the sar images
2 . sar定标与其图像辐射特性评价,包括图像的内定标和外定标,以及以天线方向图校正、比例变换和反差调整为内容的sar图像的辐射校正和增强。
