A new cost function based on the diagonalization of correlation matrices is proposed to measure the independency of output signals
摘要提出了一種新的基於相關矩陣對角化的代價函數作為衡量輸出信號獨立性的測度。 -
However, there still exists correlation between coefficients of sub - matrices after 4d - mdct. this thesis proposes a four dimensional matrix video coding method based on context to get rid of the correlation between coefficient sub - matrices further. it includes three parts as follows : firstly, this thesis presents a four - dimensional matrix video encoder and decoder model, which contains components of prediction, transform and entropy coding
實驗結果表明，該方法與傳統的二維編碼方法相比，具有高壓縮比和高圖象質量的優點;與矢量量化編碼相比，具有碼表體積小，計算復雜度低的特點;與霍夫曼編碼方法相比，在相同信噪比的條件下，對運動相對劇烈的視頻序列壓縮效果要更好。 -
This dissertation proves that formation of entanglement is smaller than mutual information. as a by - product, this dissertation also proves that there does not exist this kind of quantum state whose nearest separable state is the product of its two reduced density matrices except the state whose classical correlation is zero
證明了結構糾纏小於互信息，同時證明了對于任意的量子態（除了經典關聯為0的態） ，它的兩個約化密度矩陣的直積不可能為它的最近分離態。 -
And then, the esprit bearing estimation problem. is reformulated using fourth - order cumulant matrices instead of auto - correlation matrices. by doing so, the fourth - order cumulant matrices of additive colored gaussian noises can be suppressed
在此基礎之上，將esprit方法擴展到四階方法，用四階累積量矩陣代替自相關矩陣，實現對加性有色高斯噪聲的抑制，提高演算法的估計精度。 -
On views separation and coordinate standardization, a coordinate axis projection - based approach and an image scanning - based approach are proposed for views separation, the former reduces the compare times of 2d primitive in drawings and raises the efficiency simultaneously, the latter can separate free nember views of engineering drawing accurately and it has no correlation with complexity of primitive, then, two sets of 2. 5d coordinate systems are introduced as intermediates to relate the 2d original drawing system to the 3d space projection coordinates anfd a formal technique is developed for constructing transformation matrices between coordinates
3 .在工程圖視圖分離和坐標規格化方面，提出了改進的坐標軸投影分離演算法和基於圖像掃描的視圖分離演算法。前者減少了工程圖中二維實體的比較次數，提高了運行效率;後者可以準確分離具有任意視圖數目的工程圖，且演算法的穩定性與邊界復雜度無關。通過引入二維半中間坐標系推導出了從繪圖坐標繫到空間投影坐標系轉換的轉換運算元並給出了基於轉換運算元的坐標規格化演算法。 -
Adjusted the input parameters, a set of optimal data and covariance matrices were obtained in the statistical meaning. correlative coefficients of the cross sections were plotted in three dimension pictures with origin program. in this way, the physical meaning of the covariance matrices and the correlation between the cross section data at each energy points are displayed visually
通過調整輸入參數，最後得到在統計意義上最佳的推薦值及相應推薦值的協方差矩陣，並用origin程序畫出相關系數的三維空間圖，形象地顯示了協方差矩陣的意義及各個能點之間截面的相關性。 -
A contrast function has been built using orthogonalization time - delayed correlation matrices in time domain. the separation algorithm has been obtained by minimizing it with the frobenius norm
