圖像內插法為影像處理的一項重要技術，它時常出現在影像處理的研究方法之中。可回復式資訊隱藏已經在近年來成為資訊隱藏領域的一個重要類別，它可以在解密後，完全恢復用於藏密用的數位媒體原來的內容，而且不會對秘密資訊造成影響。本研究提出了一個高容量的資訊隱藏法，其使用鄰像素點內插法，並在藏密演算法中考慮載入圖片的內容以增進藏密法。實驗結果證明，本研究比起之前的研究，有著稍大的容量同時具有更高的PSNR值。

Image interpolation is an important technique for image processing. It often appears in image processing research methods. Reversible data hiding has become one of the important fields of information hiding category in recent years. Reversible data hiding technique can fully restore digital media which are used in steganography, and it does not affect the confidential information after decrypting. This study presents a high capacity data hiding method, which uses neighboring pixel interpolation and a steganography algorithm considering the content of the load images to enhance steganography method. Experimental results show that, compared to the previous studies in this area, our proposed method is with a slightly better capacity and higher PSNR value.
