使用C＃和EmguCV为图像提取RGB颜色直方图

I am trying to extract RGB color Histogram for an image using C# (or C++) and Emgu CV. Current:

我试图使用C#(或C ++)和Emgu CV为图像提取RGB颜色直方图。当前:

static double[] colorHistogram(Image<Bgr, Byte> img, int rStep, int gStep, int bStep)
{
     double[] histogram = null;
     return histogram;
}

No need to reinvent the wheel. Use the already available function CalcHist in EmguCV!

无需重新发明*。使用EmguCV中已有的函数CalcHist!

C#:

public static void CalcHist(
    IInputArray images,
    int[] channels,
    IInputArray mask,
    IOutputArray hist,
    int[] histSize,
    float[] ranges,
    bool accumulate
)

C++:

public:
static void CalcHist(
    IInputArray^ images, 
    array<int>^ channels, 
    IInputArray^ mask, 
    IOutputArray^ hist, 
    array<int>^ histSize, 
    array<float>^ ranges, 
    bool accumulate
)

There you go!

你去!
