Hi,
I have to perform some very very simple computer-vision tasks (such as motion detection) on image data captured by a camera, and I was considering/evaluating the possibility of using GEM to do that.
It would involve basically computing the difference between two frames, background subtraction, masking an image with another one, computing the avarage value over a rectangular portion of the image, and this kind of things.
I'm a bit lost, since I guess there are probably facilities to do such things in GEM, but I don't know where to look for.
- Are there some pix_ objects to do these kinds of operations in a
reasonably efficient way? 2) Is it possible at all to use the openGL wrappers to do such calculations in the GPU rather than CPU? Where may I find examples of that? 3) Are there some objects that already implement the latter approach and offer basic functions at a slightly higher level, such as frame-difference on a texture buffer?
If anyone can point me to any documentation/examples/tutorials specific to this kind of things, I'll be very grateful.
Or maybe this is not the kind of things GEM is suitable for? Should I forget about it and have a look at other platforms?
Thanks, m.
