"A decline set in after the 13th century, when stained-glass artists began to seek the realistic effects sought by Renaissance painters, effects to which the technique was less suited and which diverted artists from exploiting the all-important light-refracting quality of glass."

13世纪后开始衰退，当时的彩色玻璃艺术家渴望实现文艺复兴画家所追求的写实主义效果，但彩色玻璃技术无法实现这一效果，于是他们开始挖掘玻璃的反光作用。

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.

为了提高水印图像的安全性，提出了一种基于TD-ERCS混沌映射的二值水印图像的加密算法，该算法利用TD-ERCS映射产生的混沌序列加密水印图像；将离散混沌映射和二维离散小波变换相结合，研究了彩色图像水印新算法，该算法先对混沌序列加密后的水印图像进行小波变换，再嵌入到宿主图像的蓝色分量的最深层的四个子带中，嵌入位置则由广义猫映射确定；将整数小波变换和图像子采样技术应用于数字水印，提出了一种彩色图像盲提取水印算法，水印嵌入时，先对宿主图像在YIQ色彩空间中的Y分量进行子采样，并对得到的四个子图像分别进行二级离散小波变换，然后将置乱并加密后的水印图像嵌入到小波变换后的低频子带中，其嵌入位置由Logistic混沌映射产生的混沌序列确定，实现了水印的盲提取。

A colorful bird One night, a colorful bird is singing in a tree.

In this method, one of the three color components of a color image is coded using wavelet transform zerotree coding, and the component is segmented into several non overlapping subregions in the same size.

在所见到的有关这方面内容的文献中，对彩色图象的压缩编码，几乎都是对彩色图象的 3个色彩分量分别进行编码，而没有去进一步挖掘 3个色彩分量之间存在的更深层关系，其结果不可避免的是运算量大，压缩比低。
