空间平滑 meaning in Chinese

spatial smoothing

Research on an ameliorated spatial smoothing technology based on eigenspace
一种改进的特征子空间平滑技术研究
An error detecting method which can prevent the decoding error affecting the next video packet head is used , and a restoration measure for b frame based on the mv prediction which can improve the visual quality has been studied . 3 . a novel marking algorithm for ip diffserv based on the transmission condition and the different importance of video streams for decoder has been introduced
2实现了mpeg - 4的差错检测、可逆变长解码rvld和差错掩盖方法:对i或p帧纹理区的差错先用rvld进行解码,然后对残留的差错用空间插值或运动补偿方法进行掩盖,而对p帧的运动矢量mv ,利用图像的空间平滑特性进行恢复; 3针对b帧差错的复原,我们还提出了一种基于运动估计的方法。
2 a mathematical model of the reflected signal based on the frequency modulation continuous wave ( fmcw ) radar , solving the frequency - azimuth estimation of coherent signals by spatial smoothing technology , comparing the resolution of the object based on two - dim music method and that based on two - dim fft
2讨论了在接收dbf条件下，回波信号的二维谱估计技术。建立了基于调频连续波体制雷达下回波信号的数学模型，并将空间平滑技术推广到时-空二维谱估计，解决了相干信号源的频率-方位估计问题。
