Shape-Based Image Retrieval Using a New Descriptor Based on the Radon and Wavelet Transforms
In this paper, the Radon transform is used to design a new descriptor called Phi-signature invariant to usual geometric transformations. Experiments show the effectiveness of the multilevel representation of the descriptor built from Phi-signature and R-signature, compared to the powerful generic Fourier descriptor. Keywords- Radon transform; Phi-signature; R-signature; wavelet transform
