而信號的奇異點或突變點往往表現為相鄰像素點處的灰度值發生了劇烈的變化，我們可以通過相鄰像素灰度分佈的梯度來反映這種變化。 -
Compared with the pressure hydrophone, vector transducer can provide both the information about pressure ( scalar quantity ) and particle velocity ( vector quantity ) of the sound field, which offers more possibilities for signal processing. so vector transducer and its signal processing have attracted the attention of researchers both native and foreign. in this thesis, a method of correlation equations for pressure gradient transducer is presented, and the estimation of multi - signal parameters with single vector transducer is given
與傳統的聲壓水聽器相比，矢量水聽器既能獲得聲場中的聲壓這一標量信息，又能獲得聲場中質點振速這一矢量信息，這為其信號處理帶來更大的空間，因此矢量水聽器及其相應的聯合信息處理技術日益成為國內外科技工作者們研究的熱點。 -
For real world implementation of wavelet theory, we mainly focus on the selection of suitable wavelet bases and related algorithm applied in the following different aspects : in this paper, the selection of wavelet basis function is presented in detail through the investigation of traditional selection of wavelet basis and the theory of lifting scheme, an adaptive wavelet transform is put forward, and the adaptation is come from adaptive choosing between a class of linear predictors within the lifting framework according to the local gradient of the signal. we investigate the central issues such as the structure of adaptive frame and the calculation of corresponding wavelet basis function

該控制結構以支持向量機為辨識器，並用指數梯度演算法來求控製作用。 -
The paper on the basis of the study on the control of the changing slope curve paving in theory, through the study on the responses of the screed to different input signal in condition of the erected string, the controller of the transverse gradient and the floating beam on the spot experimentations, and through the analyzes the three paving design method in theory and the experimentation, on through the analyzes the three paying design method in theory and the experimentation data, provides some material solving measures to solve the changing slope curve paving
摘要根據彎道變坡攤鋪控制特性的理論研究，在工程實際中採用掛線法、橫坡控制器和浮動均衡梁進行了不同輸入激勵函數下熨平板響應的試驗研究，並通過對這3種攤鋪設計方法的理論和試驗數據的分析，提出了解決彎道變坡攤鋪的具體措施。 -
The output of vector hydrophone contains the spatial direction information, in the other word, the output has different phase gradient to signal with different direction
它是利用了矢量水聽器四個陣元的輸出所蘊含的空間方位信息，通過對一個方向信號延遲的補償相減達到此方向信號的抵消的目的。 -
The digital oral endoscope is designed and realized in this paper, which is based on the technologies of digital signal processing and database, by using gradient refractive index rod lens, that is grin - lens, and photo - electronic imaging device
摘要以梯度折射率透鏡（自聚焦透鏡）為攝像鏡頭，通過光電轉換，結合數字信號處理和數據庫技術，設計並實現了數字化口腔內窺鏡。 -
Secondly, the dynamic features, surplus torque and loading gradient features of ptss are analyzed by the couple model between the rudder and the eals. it can be concluded that the surplus torque is related directly to the velocity of the rudder, and the loading gradient is the disturbing inverse ratio from the surplus torque to the closed - loop model, which shows the scaling relationship between the input and the disturbance signal act on the eals. it also can be concluded that, under the same dynamic specification, it is more difficult to realize the small loading gradient
然後，採取把系統模型轉化為舵機和負載模擬器相互耦合作用的形式，對被動式力矩伺服系統動態特性、多餘力矩和加載梯度一一進行理論分析，得出:多餘力矩與舵機運動速度直接相關;加載梯度是在系統閉環模型中，與多餘力矩相關部分模型幅值大小成反比的系數，體現了被動式力矩伺服系統的指令信號和擾動信號之間的比值關系，從而在相同的動態指標下，小加載梯度實現更為困難。 -
For example, it is assumed that update filter utilizes local gradient information to adapt itself to the signal in the sense that smaller gradients “ evoke ” stronger update filters. as a result, the breaks of the signal won ’ t become blurring, and it
比如在更新濾波器的選擇上，對于梯度比較大的地方，也就是對應于圖中的邊緣區域，採用一種濾波器;而對于其它平滑區域，採用另一種濾波器。
