Computer vision and wavelet transforms
Qingyun Shi, Chuan Xu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1997
This paper concentrates on how to construct wavelets according to the practical needs of computer vision and image processing. At first, a theory for the construction of dyadic wavelets has been established. The resulted dyadic wavelets possess zero-symmetric or zero-antisymmetric property, and can also be fastly decayed so that they are suitable for edge detection. Then an algebra approach for the construction of orthogonal wavelets is proposed. It facilitates the selection of best wavelet for a given image processing task such as image compression.
