Enhancement of images corrupted with signal dependent noise: Application to ultrasonic imaging
(1993-11)An adaptive filter for smoothing images corrupted by signal dependent noise is presented. The filter is mainly developed for speckle suppression in medical B-scan ultrasonic imaging. The filter is based on mean filtering ... -
Iterative technique for 3-D motion estimation in videophone applications
(IEEE, 1994-04)In object based coding of facial images, the accuracy of motion and depth parameter estimates strongly affects the coding efficiency. We propose an improved algorithm based on stochastic relaxation for 3-D motion and depth ... -
A new approach to holographic video imaging: principles and simulations
(SPIE, 1992)As the importance of 3-dimensional information displays in many fields increases, more attention is given to holographic displays. Different kinds of holographic displays are reported in the literature, but the resolution ... -
A novel approach to 3-dimensional holographic television display: principles and simulations
(IEEE, 1992-03)The authors present a new technique for the display end of a holographic three-dimensional television system and describe the computer simulations. The technique is based on the reproduction of the desired pattern, in this ... -
Simulation of a holographic 3-D television display
(Bilkent University, 1990)The theory and the computer simulations of an acousto-optical holographic 3-D television display are presented in this dissertation. The technique used is based on the reproduction of the desired pattern, in our case the ... -
Simultaneous 3-D motion estimation and wire-frame model adaptation including photometric effects for knowledge-based video coding
(IEEE, 1994)We address the problem of 3-D motion estimation in the context of knowledge-based coding of facial image sequences. The proposed method handles the global and local motion estimation and the adaptation of a generic wire-frame ... -
Three-dimensional facial motion and structure estimation in video coding
(Bilkent University, 1994)We propose a novel formulation where 3-D global and local motion estimation and the adaptation of a generic wire-frame model to a particular speaker are considered simultaneously within an optical flow based framework ...
