针对CMOS 图像传感器输出的Bayer 格式的图像数据, 利用TI 公司的TMS320DM642 数字信号处理器的专用视频端口,可以实现图像捕获、数据传输的无缝连接的特点, 构建了以DM642 为核心的图像实时处理系统。在DM642 中采用两种通用方法(双线性插值、边缘检测) 和文中提出的信号相关的方法, 将从Bayer 公司的CMOS 图像传感器所捕获的8 位Bayer 格式图像数据, 转换为24 位RGB 格式彩色图像数据, 并通过PSNR(信噪比) 和NCD(归一化彩色差异规范) 两种评估方法进行检测。从实验结果可以看出文中提出的方法相对于通用方法提高了图像的信噪比, 锐化图像的边缘, 减少了图像高频信息的错误像素的数量, 提高视觉质量。(Bayer TMS320DM642)

A-Watermarking-Algorithm(MATLAB)--
盲水印提取时不需要参考原始载体图像,在信息隐藏、版权保护等方面具有更广泛的应用前景。提出的盲水印算法在分块离散余弦变换(DCT)和离散小波变换(DWT)的基础上,利用关系双方DCT系数和DWT系数在受到攻击时具有相同变化趋势的特点,采用关系嵌入和量化嵌入的自适应选择嵌入策略,较大幅度地提高了盲水印提取的鲁棒性。同时在量化嵌入中采用抖动调制,实现了水印透明性和鲁棒性调节的便捷性。大量仿真实验结果表明该算法对噪声干扰、低通滤波、JPEG压缩、对比度增强等攻击有很好的鲁棒性和透明性。关键词 数字水印盲水印关系嵌入量化嵌入离散余弦变换离散小波变换
按这篇文章的算法，自己编的matlab,没有攻击时水印提取率为1，加水印后图像PSNR有45+，。有攻击后提取率也有0.9+。(Blind watermark extraction can be fulfilled without referring to the original host image. Therefore it hasmuch
prospective applications in the fields of information hiding and copyright protection. Based on blocking Discrete Cosine
Transform (DCT) and blocking DiscreteWaveletTransform (DWT), the proposed blind watermarking algorithm uses an
embedding strategy of adaptively selecting either relationship embedding or quantization embedding. The relationship em-
bedding comes from the observation thatboth themagnitudes of coefficients concerned in the relationship usually have thesame change trend when the image is attacked. This strategy remarkably improves the robustness ofwatermark extraction.In addition, dithermodulation is used in quantization embedding, bywhich the tradeoff between transparency and robus-tness ofwatermarking can be easily adjusted. Simulation results show that the algorithm is fairly robust against the attacks such as noise, filtering, compression, and contrast )
