color image watermarking with color

基于脆弱性的水印嵌入算法，包括水印嵌入，水印攻击等(Based on the vulnerability of the watermark embedding algorithm, including watermark embedding, watermark attacks and so on)

《A RETINEX-BASED ENHANCING APPROACH FOR SINGLE UNDERWATER IMAGE》基于retinex的水下图像复原算法，非常有效(" A RETINEX-BASED ENHANCING APPROACH FOR SINGLE UNDERWATER IMAGE" underwater retinex based image restoration algorithm is very effective)

this codes describe several kind of image filters

蔡远利，西安交大，随机滤波与最优估计，非线性滤波，卡尔曼滤波，最小方差估计(optimal estimation)

4_1：生成模糊化实验图像 4_2：维纳滤波复原 4_3：约束最小二乘滤波复原 4_4：Lucy-Richardson滤波复原 4_5：盲卷积滤波复原(4_1: generate fuzzy images of experimental 4_2: 4_3 restoration Wiener filtering: constrained least squares filtering recovery 4_4: Lucy-Richardson filter recovery 4_5: Blind deconvolution filter to recover)

基于W-SVD的小波数字水印算法，包括水印生成、水印嵌入和水印检测，理解SVD奇异值分解算法。(Wavelet digital watermarking algorithm based on W-SVD includes watermarking generation, watermarking embedding and watermarking detection, and understanding SVD singular value decomposition algorithm.)

vc++图像处理原程序：图片亮度增减源代码(vc original image processing procedures : Photo brightness change source code)

说明：  hog 特征 基于matlab的 RGB提取(realize the hog feature)

分别利用均值滤波、自适应滤波和中值滤波对噪声图像g1和g2进行滤波，利用峰值信噪比对去噪性能进行比较。(Respectively, using the mean filter, adaptive filtering and median filtering images g1 and g2 noise filtering, denoising performance comparison using the peak signal-to-noise ratio.)
