Emgu CV中的Alpha混合

Question

大家好，我正在学习Emgu CV。我想执行alpha混合(addWeighted)。我有以下代码

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 and Gray)

Answer 1

尝试将灰度图像转换回彩色图像，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);
