correlation coefficient matrix 解釋
相關系數矩陣
  • correlation : n. 相互關系，相關（性）；對比；交互作用；【數學】對射，異射。 correlation index 關聯指數。 correlation mineral 對比礦物。
  • coefficient : adj. 共同作用的。n. 1. 共同作用；協同因素。2. 【數，物】系數，率；程度。
  • matrix : n （pl matrices 或matrixes）1 【解剖學】子宮；母體；發源地，策源地，搖籃；【生物學】襯質細胞；間...
  1. Two indexes was calculated to estimate the best bands union for color combination, one is optimum index factor ( oif, the sum of standard deviation divided by the sum of correlation coefficient. ), the other is the determinant of the co - variance matrix. it can be seen from the result that for color combination the original optimal bands were tm 4, 3, 7 and tm 4, 3, 5, the best mixed images were mnf1, br and ndvi

    以協方差矩陣行列式值和最佳指數值（組合波段標準差之和除以相關系數之和）為評價標準，得出對于tm原始波段而言，最佳的彩色合成組合是tm4 、 3 、 7和tm4 、 3 、 5 ；綜合幾種變換圖像的彩色合成的最佳組合是mnf1 、 br 、 ndvi 。
  2. 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。
  3. In addition, this paper choices indexes according to the correlation coefficient matrix and the actual meaning of the indexes. the method is simpler and more practicable. we compare our results with those in reference [ 8 ] and find that they are almost the same

    本文在篩選變量時把相關系數矩陣和各指標的實際意義相結合，方法簡單明了，所得結果與採用其他指標篩選方法所得結果基本相同。
  4. But the results of gray system such as absolute degree of gray incidence and matrix of absolute degree of incidence can be taken as the pleased solution of correlation coefficient and correlation matrix in the frame of statistics, as they have the statistical connote, so we can use the statistical method to handle the results until we abstain the pleased solution of what we want

    對于「灰」性較大的數據，顯然是首選灰色系統的方法，但用灰色方法處理后的結果，如灰色關聯度、灰色關聯度矩陣等，可以看作是統計范疇內的相關系數、相關陣的滿意解或近似解，仍具有統計范疇內的相關系數、相關陣的內涵。
