Color Image Analysis

我自己写的图像色彩平衡代码，其中h(i)为r、g、b的平均值，lh为h(i)的平均值，h(i)/lh-1为平衡基，s(i)为加权系数。

在MATLAB中，可以通过编程实现对图像像素的均值和熵值的计算。这是图像处理中的重要步骤，能够帮助分析图像的复杂度和信息量。 图像像素均值计算 读取图像数据：首先使用 imread 函数读取指定的图像文件。 计算均值：通过 mean2 函数计算图像的像素均值。 图像熵值计算 灰度转换：若图像为彩色图像，需先使用 rgb2gray 函数转换为灰度图像。 熵值计算：使用 entropy 函数获取图像的熵值，用于表示图像的复杂度。 通过上述步骤，能够利用MATLAB快速获得图像的基本统计信息，从而进一步深入分析图像特性。

该程序使用 Matlab 实现了 小波变换 彩色图像的 水印嵌入 和 提取。通过小波变换对图像进行多尺度分解，将水印信息嵌入到高频子带中，从而保证图像质量的同时实现水印的隐蔽性和鲁棒性。程序支持彩色图像的处理，并提供了水印提取功能，确保水印信息可以在图像受到一定程度攻击后仍然能够恢复。

This project implements the technique of color transfer between images as described in the paper by Erik Reinhard, Michael Ashikhmin, Bruce Gooch, and Peter Shirley. One of the most common tasks in image processing is changing the colors of an image. This article presents a more general color correction method, which borrows color characteristics from one image to apply to another. The algorithm follows these steps: RGB to ℓαβ color space conversion: The transformation of the RGB color space into the ℓαβ color space, where the ℓ axis represents the lightness channel, and the α and β channels represent the color-opponent yellow-blue and red-green channels, respectively. Statistical and color correction: First, the mean value is subtracted from each channel's data points. Then, the data points are scaled by factors determined by the standard deviation of each respective channel. Final conversion to RGB: The result is converted back into the RGB color space. The MATLAB code for this procedure is contained in the color_transfer_built.m file. In lines 3 and 4 of the file, the source and target variables are modified to change the source and target images for color transfer.

使用两种边界颜色和一种中心颜色创建颜色图。此方法在包含正值和负值时非常有用，中心颜色（通常为白色）代表零。用户可以定义边界和中心颜色，以及组成颜色图的段数。所有颜色输入需采用RGB三元组格式（例如[0 0 0]表示黑色）。生成颜色图后，使用：colormap(gca,newColormapName)上传到当前图形。请参阅函数文本（注释）以获取进一步的描述和示例用法。如果存在任何错误，请告诉我。
