Discretization of 3dimensional signals
===

[Symbolic Aggregate Approximation][1] talks about converting a time series (x,t) into symbols.Based on this,I have few basic queries. What if the time signal is a composite of (x,y,z,t) representing position coordinates or simply (x,y,t) for 2 dimensional image with a time stamp t. Then how do I use this tool to assign symbols/discretize.Please help.
