2d correlation
2d correlation
(OP)
I am writing a program in matlab that will do simple motion detection. This is relatively new to me and i keep coming across the term 2d correlation when doing research. Can anyone possibly explain what this terminology means and possibly suggest a better alterative.
thanks jon

RE: 2d correlation
I don't have the faintest idea how to efficiently calculate that.
The one dimensional case is called correlation, it is used in audio processing. You might have some luck in a DSP text.

If you didn't get the image processing toolbox, the 2d correlation function is not available.
