这是水涟漪效应的Qt实现。它将被用作另一个程序（ETFShop）的插件，或者如果用户愿意，可以查看代码并从代码中获得水波效应。

该程序混合高斯模型使用K（基本为3到5个） 个高斯模型来表征图像中各个像素点的特征,在新一帧图像获得后更新混合高斯模型,用当前图像中的每个像素点与混合高斯模型匹配,如果成功则判定该点为背景点, 否则为前景点。通观整个高斯模型，他主要是有方差和均值两个参数决定，,对均值和方差的学习,采取不同的学习机制,将直接影响到模型的稳定性、精确性和收敛性。由于我们是对运动目标的背景提取建模，因此需要对高斯模型中方差和均值两个参数实时更新。

应用背景主要运用在图像的点运算上，可以将RGB图像灰度化，进而二值化，也可以对灰度图像进行反色处理，进行线性变换处理。也可以将RGB图像灰度化后进行灰度拉伸和灰度均衡化处理。关键技术采用MFC界面，运用C/C++进行编程，界面清晰明了，是学习图像处理的入门程序。可以对RGB图像和灰度图像进行多种预处理，然后可以据此进行更进一步处理。
