split(image,channels);//分离彩色通道 imageBlueChannel = channels.at(); //蓝色通道的引用返回给imagBlueChannel
addWeighted(imageBlueChannel,1.0,imageGray,0.5,,imageBlueChannel);//混合后的蓝色通道 merge(channels,imageBlue);//此时蓝色通道已经变味了,
//再通过merge将三个通道重新合并成一个三通道,便得到蓝色通道图 imageRedChannel = channels.at(); //在上面处理后的基础上,分离红色通道,可得到紫色通道图
addWeighted(imageRedChannel,1.0,imageGray,0.5,,imageRedChannel);
merge(channels,imagePurple); imshow("blue",imageBlue);
