Existing DSP Libraries for Image math

Other Parts Discussed in Thread: MATHLIB

Hello,

Can anyone tell me if there are existing DSP libraries, for the c674x in the DM8168, to help with the following basic calculations?

1)  Average pixel value of an image?  The MathLib seems to support min and max value of an array, but I cannot find an "average" routine.

2)  Image addition, subtraction, etc.  For example, I need to take the absolute value of the difference between to images - abs (image A - image B) ?

I've found several DSP libraries, including MathLib, DSPLib, ImgLib, and VLIB, but none of them seem to have basic matrix math support.

Any pointers are greatly appreciated.

Thanks,

Jeff
