difference filter meaning in Chinese

差分滤波器

After removing noise by the difference filtering arithmetic , the bubbles were separated from background to obtain the pre - segmentation image by using morphological gradient and adaptive threshold
利用差影算法滤除背景干扰，依据形态梯度和自适应阈值分离前背景，得到预分割图像。
This thesis presents the latest development of nonlinear filtering theory and the appliance of divided difference filter ( ddf ) , unscented kalmen filter ( ukf ) and particle filter ( pf ) in non - cooperative bistatic radar positioning and tracking system
本文介绍了非线性滤波理论的最新进展,把ddf ( divideddifferencefilter )滤波器、 ukf ( unscentedkalmanfilter )滤波器和pf ( particlefilter )滤波器应用到了非合作式双基雷达的定位跟踪中。
