Based on the classification of images, this paper gives out four digital image steganography techniques which have good conceal effect, including low - three - bits hiding strategy, odd - even of hypo - low bit hiding strategy, deviation of adjacent - field hiding strategy and self - adaptive deviation of adjacent - field hiding strategy. on digital watermarking aspect, this paper gives two blind watermarking strategies which have good conceal effect and high robustness, they are single - watermarking strategy based on minimal - value exchanging and multi - watermarking strategy which hides the same watermark copy on the different parts of an image
在對圖像進行了分類的基礎上，本文給出了四個具有較好掩密效果的數字圖像隱寫策略，包括低三位隱藏策略、次低位奇偶策略、鄰域方差策略和自適應鄰域方差策略；在數字水印方面，提出兩個掩密效果好且魯棒性較高的數字圖像盲水印策略，分別為基於最小值交換法的單一水印策略和嵌入同一水印多個副本的多水印策略。 -
It can be found that the two models can measure the credit risk better and their numerical values of the var are relatively close, which means that at a certain confidence level, the portfolio ' s maximum loss calculated under the default model is familiar to the maximum loss in value resulted from the credit metrics model. however, under the default model the standard deviation of the loss of the loan is a bit more than the one which deviates from the average value of the loan under the credit metrics model ; in addition, the conclusion also demonstrates that the two models have some differences in the measuring the capital reserve to some extent
從結果可以看出，這兩個模型均能較好地度量銀行貸款信用風險，其計算所得的var值比較接近，說明在給定置信水平下所能達到的最大損失和所能達到的價值上的損失在數值上是相近的；不過，違約模型下貸款損失的標準差要比creditmetrics模型下的貸款價值偏離其均值的標準差要大些；此外，結論還表現出二者在計量資本金要求上有所差異。
