What is the difference between first order spatial statistics and first order temporal statistics?
Thanks.
Isn’t it obvious? One deals with space, the other with time.
(In other words, I don’t know. I’ll do a little digging and see if I can come up with anything.)
In a system dealing with both time and space as a dimension, there can be very different statistics depending on which dimension you consider. Think about digital video. If you just look at one frame as a regular 2-D image, the pixels will have some set of statistics (the mean intensity, the correlation between neighboring pixels, etc.). These would be spatial statistics. If you just focus on one pixel and follow it from frame to frame, there would be a completely different set of statistics (again the mean intensity, and the correlation from one frame to the next). These would be temporal statistics.
The “first-order” part generally means that the are considering only the mean value (the 1st moment in statistics parlance), and not any “higher-order” statistics like variance (standard deviation) or correlation.
[Church Lady] Well, isn’t that spatial ! [/CL]
