چکیده

A novel method for enhancement of digital X-ray images of bones is presented in this paper. It has come to observation that the proposed method based on the Gaussian higher order derivative shows an appreciable enhancement of edges in digital X-ray images of bones that can be used for detection of various bone deformities as well as for the better understanding of the bone structure. We have achieved a level of improvement in distinguishing the bone information from the other parts of the digital X-ray images.

Discrete approximations of the affine Gaussian derivative model for visual receptive fields

The affine Gaussian derivative model can in several respects be regarded as a canonical model for receptive fields over a spatial image domain: (i) it can be derived by necessity from scale-space axioms that reflect structural properties of the world, (ii) it constitutes an excellent model for the receptive fields of simple cells in the primary visual cortex and (iii) it is covariant under affi...

Numerical Solution of Caputo-Fabrizio Time Fractional Distributed Order Reaction-diffusion Equation via Quasi Wavelet based Numerical Method

In this paper, we derive a novel numerical method to find out the numerical solution of fractional partial differential equations (PDEs) involving Caputo-Fabrizio (C-F) fractional derivatives. We first find out the approximation formula of C-F derivative of function tk. We approximate the C-F derivative in time with the help of the Legendre spectral method and approximation formula o...

On the Performance of Ultra Wideband Radio in Stochastic Tapped Delay Line Model of the Ultra Wideband Channel

This paper demonstrates the performance of Ultra Wideband (UWB) systems in the Stochastic Tapped Delay Line (STDL) model of the UWB channel with RAKE receiver. System models are based on Direct Sequence Code Division Multiple Access (DS-CDMA) principle. The system has been studied in presence of multiple user interference and Gaussian noise. During the analysis, various types of narrow, sub-nan...

On B-Spline Framelets Derived from the Unitary Extension Principle

Spline wavelet tight frames of [20] have been used widely in frame based image analysis and restorations (see, e.g. survey articles [15, 22]). However, except for the tight frame property and the approximation order of the truncated series (see [13,20]), there are few other properties of this family of spline wavelet tight frames to be known. This paper is to present a few new properties of thi...
