Adaptive reversible video watermarking based on motion-compensated prediction error expansion with pixel selection

Vural, Cabir; Baraklı, Burhan (SPRINGER LONDON LTD, 2016)

In this study, a motion-compensated prediction error expansion-based adaptive reversible video watermarking algorithm is proposed. Blocks of motion-compensated frames are classified as smooth and non-smooth according to ...
Blind image deconvolution via dispersion minimization

Vural, Cabir (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006)

In linear image restoration, the point spread function of the degrading system is assumed known even though this information is usually not available in real applications. As a result, both blur identification and image ...
Blind image resolution enhancement based on a 2D constant modulus algorithm

Vural, Cabir; Kara, Fatih (IOP PUBLISHING LTD, 2008)

In almost all super-resolution methods, the blur operator is assumed to be known. However, in practical situations this operator is not available or available only to a finite extent. In this paper, a super-resolution ...

Convergence analysis of blind image deconvolution via dispersion minimization

Vural, Cabir (JOHN WILEY & SONS LTD, 2006)

A new non-linear adaptive filter called blind image deconvolution via dispersion minimization has recently been proposed for restoring noisy blurred images blindly. This is essentially a two-dimensional version of the ...
Fast and robust software-based digital phase-locked loop for power electronics applications

Özdemir, Ayhan; Yazıcı, İrfan; Vural, Cabir (INST ENGINEERING TECHNOLOGY-IET, 2013)

In this study, a fast and fully software-based algorithm for digital phase-locked loop (PLL) is proposed via a new hybrid approach in software and hardware by using an advanced digital signal processor architecture. The ...
Recursive blind image deconvolution via dispersion minimization

Vural, Cabir (JOHN WILEY & SONS LTD, 2005)

This paper presents an adaptive autoregressive (AR) approach to the blind image deconvolution problem which has several advantages over standard adaptive FIR filters. There is no need to figure out the optimum filter support ...
Reversible video watermarking through recursive histogram modification

Vural, Cabir; Ibrahim Yildirim (SPRINGER, 2017)

In this study, a new reversible video watermarking method is developed. Unlike the existing reversible video watermarking algorithms that are based on motion compensated prediction or interpolation error expansion, motion ...
Reversible video watermarking using motion-compensated frame interpolation error expansion

Vural, Cabir; Baraklı, Burhan (SPRINGER LONDON LTD, 2015)

In this study, a reversible video watermarking method based on motion-compensated frame interpolation error expansion is developed. Interframe correlation is exploited more efficiently as a result of using motion-compensated ...
