The Radon transform constitutes a fundamental concept for x-rays in medical imaging, and more generally, in image reconstruction problems from diverse fields. The Radon transform in Euclidean spaces assigns to functions their integrals over affine hyperplanes. This can be extended so that the integration is performed on affine k-dimensional subspaces, the corresponding transform is called k-pla...

We describe a dynamic software watermark embedded in the memory trace of an executing Java program. Our approach is a generalisation of the spread–transform watermarking technique developed for use in the multimedia domain. We show how the spread–transform paradigm enables the embedding of dither modulation watermarks in a Java program and report its robustness to realistic additive noise attacks.

The demand for low voltage DC (LVDC) distribution systems is increasing due to the rapid development of power conversion technology, increase DC-based digital loads, and expansion distributed generation (DG). For stable operation LVDC system, it necessary develop a protection method. In this paper, fault section estimated using wavelet transform (WT) in system. classified into line bus. charact...

background: early and non-invasive determination of blood glucose level is of great importance. we aimed to present a new technique to accurately infer the blood glucose concentration in peripheral blood flow using non-invasive optical monitoring system. methods: the data for the research were obtained from 900 individuals. of them, 750 people had diabetes mellitus (dm). the system was designed...

Background: There is no method to quantify the spatial complexity within colon polyps. This paper describes a spatial transformation that translates the tissue architecture within a polyp, or a normal colon lining, into a complex sinusoid wave composed of discrete points. This sinusoid wave can then undergo the Fast Fourier Transform to obtain a spectrum of frequencies that represents the sinus...

The optical behaviour of the (human) cornea is often characterized with the Zernike-coefficients derived via the Zernike-transform of its optical power map. In this paper, a radial transform based on the Chebyshev-polynomials of the second kind is suggested for a surface-based, rather than an optical power map based representation of the cornea. This transform is well-suited for providing compa...

A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene. Its lowcomputational complexity and fast runtimes makes this method well-suited for real-time vision applications. The performance of the transform is demonstrated on a wide variety of images and compared with leading techniques from the literature. Both as a facial feature detector ...
