Multiscale Generic Fourier Descriptor for Gray Image Retrieval
Haihong Wu · 2005
A large number of gray image are created and available on the Web, since more and more gray images and digitizing tools are developed for different applications. The techniques for content-based gray image retrieval is necessary. In gray image retrieval system, we propose multiscale generic Fourier descriptor(MGFD), which integrates generic fourier descriptor with multiscale anslysis.The experimental results show that MGFD is not only capable of multiscale anslysis, but robust against noise and other changes of image and it is also invariant to rotation and scale. It have a precise result in gray image retrieval.
