What is the equivalent of “getTickFrequency” from OpenCV in C# EmguCV?

Question

I am converting this code from C++ to C#

double freq = getTickFrequency() / 1000;

I can't find the equivalent of getTickFrequency in EmguCV in C#.

Answer 1

Just like my previous question, I didn't find an explicit function for getTickFrequency in EmguCV. The only solution I found is to rewrite the function using the open source of OpenCV OpenCV Core

[DllImport("Kernel32.dll")]
private static extern bool QueryPerformanceFrequency(out long lpFrequency);
double GetTickFrequency()
{
    QueryPerformanceFrequency(out long freq);
    return (double)freq;
}

I thing EmguCV should be revised to add these missing parts with good documentation.
