Affine Invariant Dynamic Time Warping and its Application to Online Rotated Handwriting Recognition

Abstract

Dynamic time warping (DTW) has been widely used to align and compare two sequences. DTW can efficiently deal with local warp or deformation between sequences. However, it can't take account of affine transformation of sequences, such as rotation, shift and scale. This paper introduces a novel affine invariant dynamic time warping (AI-DTW) method, which… (More)
