An effective image steganographic scheme based on wavelet transformation and pattern-based modification
Summary(摘要):
In this paper, a new scheme for image steganography is presented.
在這篇文章中，介紹新的計畫有關數位圖像偽裝

The proposed scheme has the ability to hide secret message in a digital image.
目標是把秘密訊息藏在圖像中

We call the scheme the pattern-based image steganography (PBIS).
我們把它稱為基本樣式圖像偽裝(PBIS)

First, PBIS does discrete wavelet transformation (DWT) on the digital image;
首先，使用分離(不連續?)微波(?)轉變在數位圖像

separates the transformation result into nonoverlapping blocks, and classifies the wavelet coefficients of these blocks into several patterns.
分開的轉變使得區塊不重疊，這些分類的微波係數區塊會有這些模式.
這一行...完全看不懂

The secret message is embedded into the image by changing the coefficients' patterns.
秘密訊息被放在圖像裡藉由改變係數模式

The performance and reliability of PBIS are shown in the experimental results.
PBIS的成果和可行性顯示在實驗結果

The quality of the stego image of the proposed scheme is very close to that of the original one.
隱密圖像的質量和原本的是非常相近

Moreover, our scheme can be survived under JPEG lossy compression.
此外，這可以活在(適用?)在JPEG的有損壓縮下
