<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I am triing to implement 2 filters: the first one to <STRONG>compute the complex conjugate</STRONG> of a complex image, the other one <STRONG>to compute the multiplication of 2 complex</STRONG> images. </DIV>
<DIV> </DIV>
<DIV>I saw that there are already a lot of files to compute operations on complex images:

<P><FONT size=2></FONT> </P>
<P><FONT size=2>So I suppose that, the same way <STRONG>imag()</STRONG> exists, there shoud be a <STRONG>conjugate()</STRONG> operation that is already existing. How and where can I see a list of operations or operators existing for complex numbers. This could help me a lot to compute my owns filters.</FONT></P>

<P><FONT size=2>Thanks for help,</FONT></P>
