image domain meaning in Chinese
图像域
Examples
- For wideband noise interferences , this dissertation studies wavelet packet threshold method and uses it to suppress wideband noise interferences in signal domain and image domain
对于宽带噪声干扰,本文研究了小波包阈值方法,并将之应用到信号域和图像域来抑制宽带噪声干扰。 - In chapter 5 , all above algorithms are tested with the true raw data of an x - band sar . the test results of different algorithms are compared in both data domain and image domain
第五章采用真实合成孔径雷达原始数据对各种算法进行验证，分析了各种算法的优势和特点，在数据域和图像域对不同算法的压缩性能作了定量的比较。 - On the other hand , in image domain , spatially varying point - spread function ( svpsf ) is defined to demonstrate how the effects of complex scattering centers which cause scattering model mismatch can be interpreted as being due to a svpsf acting on a ideal scatterer
同时在图像域引入二维空变点展布函数( svpdf )来解析表达非点散射机制对理想“点”的展布作用。 - Geometric distortion is traditionally corrected by an image resampling operation which is applied as a post - processing step to pfa . the scene size limits of pfa presented by range curvature qpe , can be alleviated by using an efficient image domain space - vairant post - filter
通常采用图像域插值的方法校正几何失真,而利用空变滤波器使散焦的点重新聚焦,这些校正方法可以减轻距离弯曲对成像范围的限制。 - Based on theoretical deductions and data simulations , this dissertation analyzes properties of echo data in time domain , frequency domain and wavelet packet transform ( wpt ) domain . we also analysize properties of complex image data in image domain , image frequency domain and image wavelet packet transform domain . several methods are proposed for jamming suppression in signal domain and image domain respectively
本文在理论推导、数据仿真的基础上,分析了原始回波数据在时域、频域和小波变换域的特征以及复图像数据在图像域、图像频域和图像小波变换域的特征,提出了几种行之有效的信号域和图像域抑制方法。
