video Spatial Pixel values stored into Memory Temporal Video consists of image frame sequence

I am a beginner in learning image processing, and I am a bit confused with the concept of spatial and temporal characterization. so for Spatial characterization, it's like a 2D map where it contain some statistical information about the map? And in terms of the temporal characterization, the value is with respect to time? What does it mean and why do we care? Thanks!

Temporal characterization occurs when you have a series of images taken at different time. Correlations between the images are often used to monitor the dynamic changes of the object.
Spatial characterization applies when you are analyzing one image. It includes but not limited to the coordinates, intensity, gradient, resolution, to name only a few.
Check this paper on blood vessel analysis to get more details among the two.

thank you very much for your response! I am much appreciated! – a077456 Dec 28 '13 at 21:47
Spatial = Space Example, Image consist of pixel values which needs memory space to store. Spatial information = Pixel values stored into Memory
Temporal = Time Example, Video consists of image frame sequence. With respect to time the frames are changed in video. This is called Temporal Information.
