“…Under this framework, a given mesh is represented by a coarser mesh and a set of vectors, called Wavelet Coefficient Vectors (WCV), used for encoding the details. 3D wavelet analysis was used for various applications including filtering [16], mesh compression [17,18], subdivision [19], as well as information hiding [20,21,22,23,24,25]. A 3D wavelet-based watermarking algorithm was proposed by Kanai et al [20], which modifies the ratio between the norm of a WCV and the length of its support edge.…”
