A Multiresolution Stereo Matching Algorithm Based on Dyadic Wavelet Transform

This paper proposes a new algorithm for stereo matching which utilizes the wavelet transform theory developed recently. The multiresolution zero-crossings of dyadic wavelet transform are used as matching primitives. The matching approach utilizes the characteric of wavelet transform zero-crossings and the power matching constraint to resolve the ambiguity of matching in local feature similar and global matching consistency, and the system uses a new coarse-to-fine multiresolution matching stragy. Experimental results show that the algorithm is simple, reliable and capable of adaptable coping with complicated real scenes.
