“…In addition, the comparison between GFIF and IFVR is made to demonstrate the necessity of restricting the combinational noise level. The method consists of three cascaded steps, whose combined observations for each step are selected as EWL (φ (0,−1,1) − p(0,1,1)), WL (φ (1,4,−5) − p(1,1,1)), and NL (a1 φ − 0,0)), of which a is corresponding combined factors, referred to by [7,17]. Note that the LAMBDA algorithm is used for the ambiguity resolution of IFVR, GFIF, and GBIR, in which the …”
