image filtering using .NET Compact Framework

[FCBfreak]

Is it possibly to apply filters to captured images under the .NET
Compact Framework?

I would like to port an existing C# managed application (full .NET
Framework) to a WinCE embedded development board (which only
supports .NET Compact Framework).

Captured images from webcam device are being loaded into memory and
the developed application then converts these images (image processing
by using gaussian filter etc.) into perceptible audio signals, which
point out the direction of the target.

But as I'm seeing it now, implementing a gaussian filter to smooth out
irrelevant parts in the captured frames requires the namespace
"System.Drawing.Imaging" (to edit images and save information in
bitmaps), this namespace is available when using the complete .NET
Framework, but isn't supported in the .NET Compact Framework.

Maybe I can use the p/invoke method (managed code calling unmanaged
code) to apply image filtering?

You would have to do all of that work yourself. I don't know if there's
even something to P/Invoke - you might need to write your own filter for
that even.

So you'e saying the original C# code that implements the filtering
can't be reused at all?

Correct. The namespaces used on the desktop just don't exist on the device.
Of souce you could create them and then the app code would work, but you'd
have to write all of the imaging libraries yourself.
