Emgu CV中的Alpha混合
问题描述:
嗨,我正在学习Emgu CV。我想执行alpha混合(addWeighted)。我有以下代码Emgu CV中的Alpha混合
Image<Bgr, Byte> image = new Image<Bgr, Byte>(filename);
Image<Gray, Byte> grayImage = image.Convert<Gray, Byte>();
Image<Bgr, Byte> blendImage;
如何alpha混合这两个图像? (Bgr和Gray)
答
尝试将灰度图像转换回颜色,然后将它们混合。
Image<Bgr, Byte> grayBGRImage = grayImage.Convert<Bgr, Byte>();
double alpha = 0.5; // Or however you would like to blend them
double beta = 1 - alpha;
double gamma = 0;
Image<Bgr, Byte> blendImage = image.AddWeighted(grayBGRImage, alpha, beta, gamma);
