zero cross detection 中文意思是什麼
zero cross detection
解釋
過零檢測-
The cross - zero detection of wavelet transform could detect the gradation image sudden change information, at the same time it could be express the characteristic information the original map ( namely image function plants " jump point " )
小波過零檢測可以很好的檢測到灰度圖像的突變信息,同時可以很好的表示出原圖像灰度跳變(即圖像函數種的「拐點」 )的特徵信息。 -
A novel method of zero cross for 3d biomedical image edge detection
一種基於邊緣檢測的跳頻檢測演算法研究 -
In this paper, the real - time detecting method for harmonic current need only that the constructed voltage system be in step with the real voltage system ( which can be obtained by cross - zero detection to voltage waveform ), meanwhile, we have testified in concerned chapter that the phase is not important for the constructed voltage system
本文所提出的諧波電流實時檢測方法,其前提只是要求構造系統與原有電壓系統同步(這可以通過對電壓波形的過零檢測來實現) ,而對于構造系統的相位卻沒有嚴格的要求,本文並在相應位置給予了其證明。
