Invariant Object Recognition Using Radon-based Transform
نویسنده
چکیده
The properties of the Radon transform are used to derive the transformation invariant to translation, rotation and scaling. The invariant transformation involves translation compensation, angle representation and 1-D Fourier transform. The new object recognition method is studied experimentally in two domains, mammogram labels recognition and face recognition. For mammogram labels, the recognition accuracy is 97%, while in case of faces it reaches 96%.

Three feature functions based on Radon transform for image retrieval and object recognition
In this paper we propose a novel approach called three feature functions based on Radon transform directly. The corresponding features are defined as the symmetry of the shape, the width of contour, the fullness of the shape. They reveal the information of visual and the inner structures of shape using characteristics of Radon projective space. Theoretical and experimental results verify that t...
متن کاملInvariant pattern recognition using the RFM descriptor
A pattern descriptor invariant to rotation, scaling, translation (RST), and robust to additive noise is proposed by using the Radon, Fourier, and Mellin transforms. The Radon transform converts the RST transformations applied on a pattern into transformations in the radial and angular slices of the Radon transform data. These beneficial properties of the Radon transform make it an useful interm...
متن کاملHand Gesture Recognition using Gabor and Radon Transform with Invariant Moment Features
Abstract: In this article we present problem recognizing gestures and signs executed by hands. Gesture recognition is the process by which gestures formed by a user interact with the computer or is the element of the special signs language to convey meaning.We propose a methods for the recognition of hand gestures using Gabor wavelets (GW ), Radon transform (RT ) and texture features for gestur...
متن کاملSimilarity transformation parameters recovery based on Radon transform. Application in image registration and object recognition
The Radon transform, since its introduction in the beginning of the last century, has been studied deeply and applied by researchers in a great number of applications, especially in the biomedical imaging fields. By using the Radon transform properties, the issue is to recover the transformation parameters regarding the rotation, scaling and translation, by handling only the image projections a...
متن کاملRobust Image Watermark Using Radon Transform and Bispectrum Invariants
Image watermark that is resistant to geometric distortion is remained to be an unsolved problem. Difficulty of the probelm comes from the situation that the watermark should be extracted without any information of the original image. In this paper, we review this problem and propose a new watermarking scheme based on invariant pattern recognition theory. We propose an invariant watermark using ...
