Fig. 1From: Data compression in ViSAR sensor networks using non-linear adaptive weightingGeneral positions for underestimate pixels. There are two general positions for underestimate pixels (square symbol) which should be computed by an LMMSE-based interpolator [19]: the left part shows a position with two orthogonal directions of 0 and 90 degrees, and the right shows another position with orthogonal directions of 45 and 135 degrees [7]Back to article page
