Image Retrieval Based on Wavelet Transform and Fourier Descriptors
Liu Mei · Systems engineering and electronics · 2003
In this paper, a multi-resolution edge detection arithmetic based on wavelet transform is applied to image with noise. It has a better performance than classical edge detection operators. Fourier descriptors which do not change with translation, rotation and scale change are analyzed. Then multi-resolution edge detection arithmetic based on wavelet transform and Fourier descriptors are applied to shape-based image retrieval. The experimental result proves that retrieval ratio is high in case of background rotation, translation and scale change.
