    Abstract: 根據修改的視覺密碼,張教授提出了一種新的秘密彩色影像分享機制,使用少許的計算便能將彩色機密影像隱藏於多張偽裝影像中,並能從這些分享影像完美無誤地將機密影像還原。然而,製作出的偽裝影像中有嚴重的雜訊存在。本論文提出一個改良型隱藏演算法來避免產生有雜訊的偽裝影像,同時保留原秘密彩色影像分享機制之完美無誤的還原能力。
    Based on modified visual cryptography, professor Chang introduced an advanced secret sharing scheme for hiding a colored image into multiple camouflage images with a few additional computations. The technique can achieve a lossless recovery of the secret image. However, the generated camouflage images contain excessive noise. This paper presents an improved hiding algorithm to avoid generating noiseless camouflages with achieving the same recovery capacity as the original scheme does.
