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,然後提取亮度通道y ,將其進行小波變換,然後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。 -
The processes include the deposition of the waveguide film, the design and fabrication of the mask pattern, the lithography, the metal coating with a magnetic sputtering, the lift - off process for the metal mask, the dry deep etching by icp, the slicing of the wafer, the polishing of the cutting edge, the fiber - to - waveguide alignment and at last, the performance testing. some edg chip samples are fabricated
