This arithmetic divides the wavelet coefficients of carrier image into 27 - classes by the background luminance , the texture and the edge mask character of visual system ; then after encrypting watermark image with magic cube transformation , the ycbcr model is employed , it embeds the watermark sequences in the carrier image with different intensity according to the coefficients “ classes of carrier image in y channel 首先,將載體rgb圖像轉換到ycbcr顏色空間,然后提取亮度通道y ,將其進行小波變換,然后利用人眼視覺模型對載體圖象分解后的小波系數進行分類。其次,對有意義的水印圖像分別進行3次不同的魔方置亂,得到3個隨機水印序列。

Guided by brand recognition , “ marketing magic cube for school brandtm ” of three - men try to achieve the expected goals by spreading brand culture , stimulating brand imagination , consolidating brand memory , communicating in depth and forming brand loyalty 在品牌識別的基礎上,通過一系列的營銷活動,傳播品牌文化,激發品牌聯想,加強品牌記憶,建立深度溝通,形成品牌忠誠,達成預計目標。

Firstly , a natural number chaotic sequence is created with the key . then the image matrix is transformed with this chaotic sequence , using the magic cube transformation . the results indicate that the proposed algorithm can get a satisfying effect 提出了一種在小波域內的基于混沌序列的模運算數字圖像加密解密算法和基于混沌序列的魔方變換數字圖象加密解密算法。

Break up the magic cube elements and endow them a certain function and a new combination like cells so that we can got a diversified , flexible , multi - culture and acclimation products 將魔方各元素分解,并賦予他們一定功能,再像細胞一樣重新排列組合,以達到形態多樣、功能靈活、文化多元、適應環境的特點。
