storedColorMap is undefined but potentially used.

It would be faster if you told us which section of that code produced the [] -- or is the [] only produced in your attempted single-loop version which you did not post?

my first loop is producing [],i.e mean,std dev,variance

Either your dirlist is empty or your image files are all empty.

Use the debugger to check that you really are executing the loop, and to check the progress of the calculations.
