Abstract
AbstractAs a novel elastic image matching technique, piecewise linear 2D warping (PL2DW) is investigated. In PL2DW, the mapping of each row of one image to another image is given by the linear interpolation of the mapping of several points, called pivots, prepared on the row. The linearization realizes a dynamic programming (DP)‐based algorithm with feasible computational complexity, although many DP‐based algorithms for elastic image matching are intractable. Experimental results show the effectiveness, and particularly the computational feasibility, of PL2DW. © 2001 Scripta Technica, Syst Comp Jpn, 32(12): 1–9, 2001
