Stable multiresolution feature extraction using translation- and scale-invariant adaptive wavelet transform
Huilin Xiong, Tianxu Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
In this paper, we propose an translation- and scale- invariant adaptive wavelet transform, and according to this adaptive wavelet decomposition, we construct a stable multiresolution feature vector of images which is translation-invariant and scale-invariant. At end, we give some experiment results to demonstrate the stability of this feature vector under translation and scale transform.
