Escaping Depressions in LRTS Based on Incremental Refinement of Encoded Quad-Trees

Table 2

The contrast between EQ LRTS and original LRTS on the runtime.

Methods	Terrains
	Strips	Long strips	Corners	Grooves	Complexes
	Average runtime (ms)
LRTS on Quad-tree	1.06	2.91	10.28	12.11	16.30
LRTS on uniform cells	0.74	4.40	6.02	6.80	10.87
Average RR	1.84	0.70	2.20	2.28	1.60
