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 m...

Multiscale Fourier Descriptor for Shape-Based Image Retrieval
The shapes occurring in the images are important in the content-based image retrieval. In this paper we introduce a new Fourier-based descriptor for the characterization of the sh...

A Geometric Invariant Shape Descriptor Based on the Radon, Fourier, and Mellin Transforms
—A new shape descriptor invariant to geometric transformation based on the Radon, Fourier, and Mellin transforms is proposed. The Radon transform converts the geometric transform...

Histogram of radon transform. A useful descriptor for shape retrieval
In this paper we present a new descriptor based on the Radon transform. We propose a histogram of the Radon transform, called HRT, which is invariant to common geometrical transfo...

A New Wavelet-Based Texture Descriptor for Image Retrieval
This paper presents a novel texture descriptor based on the wavelet transform. First, we will consider vertical and horizontal coefficients at the same position as the components o...
