“Complex conjugate” of a ComplexImage object, for cross-correlation

Question

I am trying to do cross correlation between two images, using the AForge framework. To do this I need to get the complex conjugate of a ComplexImage object.

I didn't find any tool to do this in the AForge framework, and using System.Numerics.Complex.Conjugate() returns an error (of course, I can't convert an image into a complex number).

How can I do this ? Is using loops and working pixel-by-pixel the only way ? This seems really tedious and time-consuming. Or is there a way to implement the cross-correlation without using a complex conjugate ?

正如@Paul R所说：“对于空间域中的纯真实图像，复共轭与原始复数相同。”
