移变 meaning in English
shiftvariant
Examples
- The image inverse filtering with polynomial approximation and the image recovery in spatially variant systems
用多项式近似的图象逆滤波及空间移变系统图象的恢复 - K method fft the echo signal , and transform it to the ? k domain , it is the most effective method to implement the 2 - d sar shifting filter . however , stolt interpolation will increase the imaging time , and will influence the quality of the image
波数域成像算法是sar二维移变滤波器的最有效实现,但是stolt插值运算将带来附加的计算量并且频域插值精度对成像质量有一定影响。 - The ccd space remote sensing camera imaging is different from traditional film imaging . the grain dimension of photosensitive emulsion is so small compare with the blurs of optical system that it can be ignored . but the ccd pixel dimension is a few times of the blurs of optical system
这里则采用模拟试验及计算机仿真的方法来研究在空间移变条件下的ccd遥感相机的影像分辨力和像质问题，这种研究不仅在理论上是一种补充，在工程实践上也很有实际意义。 - Under the condition of space moving changed system and the engineering practice , a function of the pixel dimension , the mtf of ccd sensor imaging , the width of target strip and the image motion has been acquired 4 . under the condition of one pixel image motion and the nyquist frequencies , adopting the convolution method , the ratios of the mtf with image motion to the idea mtf are 0 . 667
这样就为在工程实际中，在空间移变条件下，求取了ccd探测器影像的mtf 、像元尺寸、影像分辨力和像移量四者之间的一个简洁的函数关系:材了万二1一( 2 + n一m ) 2 ? o4n4 .采用仿真的方法和采用卷积方法的比较。
