gray scaling
解釋
採取灰點標準-
Our view is that gray coding not only has good global searching ability but also good local searching ability. studying on fitness scaling
本文認為，格雷碼編碼方法不但具有良好的局部搜索能力而且具有較好的全局搜索能力。 -
This paper will introduce every step of implement techniques of algorithm in detail, analyze binary coding and gray coding, improve the method of fitness scaling and combine chaos with genetic algorithm
本文詳細介紹了遺傳演算法的各個步驟的主要的實施技術，分析了二進制編碼和格雷碼編碼兩種編碼方法，改進了適應度變換的實施技術。 -
Image preprocessing includes transformation of image format, scaling of image size, smooth and noise - removing, gray level distribution normalization
圖像的格式轉換、尺寸縮放、平滑去噪以及灰度的正規化組成了前期預處理過程。 -
In order to adapt the scheme to both the color image and the gray image, while embedding the watermarking into the image, the scaling factors are determined by the local luminance feature and texture features of the image. it can improve the embedding strength and the watermarking robustness. from the experimental results, the stego - images are extremely robust to common image processing such as median filter, jpeg compression and denoising after adding the stochastic noises
2 、提出了一種新的基於小波變換和紋理特徵的數字水印演算法，該演算法依據從圖像小波域提取出的紋理特徵來選取水印的嵌入位置，較好地利用了圖像的紋理區域，既能掩蔽較多的噪聲，又能較好地抵抗jpeg壓縮等一般性攻擊，調節了數字水印技術中存在的不可見性與魯棒性之間的矛盾。
