Precision (%)	92.21(97.18)	89.35(90.75)	91.30 ( 95.00 )	92.77	84.97	90.11
RMSE (pixels)	2.09(2.09)	2.08(2.10)	2.09 ( 2.10 )	2.03	2.09	2.04

Total time span (t1 to t100) is divided into two slots corresponding to fixed (t1 to t66) and variable (t67 to t100) number of cells, and average metric scores were obtained by averaging scores in each time slot.
