motion artifact 中文意思是什麼
motion artifact
解釋
運動偽影-
High frequency electri - cutlery and motion artifact are important reasons of measurement error and wrong warning message
高頻電刀的干擾，和運動偽差，是造成測量誤差和誤報警的重要原因。 -
While motion artifact is caused by non - regular shiver of patient. given enough time delayed, motion artifact signal have poor or even no self - corelation. so do the other sort of interaction noise. thus these two category of signal may be distinguished by there characteristic of self - correlation, and the noise may be eliminated
運動偽差，一般都是由被測對象不自覺地或不受控地抖動引起，因而只要時間足夠長，運動偽差信號在時間上相關性極弱或先後不相關;同樣，其他的高低頻干擾如高頻電刀的干擾亦是如此。 -
Motion artifact cancellation in electrogastrograms using reconstruction of the wavelet transform modulus maxima
小波變換模極大值重建方法消除胃電檢測中的運動偽跡 -
With the theory of wavelet transform and reversible integer - to - integer wavelet transforms based on shifting frame used in image / video compression field introduced, a new real - time implement of speck algorithm using dsp chip is provided. then the technology of motion estimation and motion compensation is discussed and an adaptive technique for the wavelet video codec to reduce the " block artifact " is presented. and the implement of the wavelet video compression system using adv611 chip is discussed next with the performance emulation result
在系統討論了小波理論在圖像視頻壓縮編碼領域的應用后，結合dsp技術提出一種基於dsp應用的實時低存儲需求的改進speck圖像編碼器；隨后探討基於小波變換的實時視頻編碼器的實現，在論述運動估計與補償技術的基礎上，針對應用空域運動估計補償技術的低比特率小波視頻編碼器提出一種自適應消除塊效應的技術；並討論了基於adv611晶元的視頻壓縮系統的壓縮性能；最後提出一種基於dsp平臺具有極低時延的小波視頻混合編碼方案，對該方案的壓縮性能進行了討論並給出初步的硬體實現方案。
