An estimation approach for Gaussian distribution on degraded images

Hybrid Approach for Denoising of Degraded Images

Denoising of images using hybrid approach has been a predominant scenario in the current trends. The hybrid approach refers in giving up a combined framework to utilize the advantage of both Fourier and wavelet domain schemes. The noisy images including their Region of Interest (ROI) can yield encouraging results, when obtained through the proposed hybrid approach when comparing to the single t...

Estimation-theoretic approach to the deconvolution of atmospherically degraded images with wavefront sensor measurements

Deconvolution from wavefront sensing (or self-referenced speckle holography) has previously been proposed as a post-detection processing technique for correcting turbulence-induced wavefront phase-errors in incoherent imaging systems. In this paper, a new methodology is considered for processing the image and wavefront-sensor data in which the method of maximum-likelihood estimation is used to ...

An iterative approach for estimation of efficiency by weighted distance

An Approach for the Estimation of Aggregate Potential Telecommuting Demand

Development of technology has made possible the invention of innovative and modern methods to solve partially the problems caused by traffic congestion, through decreasing the need for physical transportation; one such method being telecommuting. Few predictions have been reported regarding its aggregate demand at the level of a city, generally because of the complexity and multi-dimensionality...

Estimation of Parameters for an Extended Generalized Half Logistic Distribution Based on Complete and Censored Data

This paper considers an Extended Generalized Half Logistic distribution. We derive some properties of this distribution and then we discuss estimation of the distribution parameters by the methods of moments, maximum likelihood and the new method of minimum spacing distance estimator based on complete data. Also, maximum likelihood equations for estimating the parameters based on Type-I and Typ...
