Efficiency of object motion extraction using disparity signals

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Simultaneous object extraction and disparity estimation using stochastic diffusion

This paper proposes a Maximum A Posteriori (MAP) algorithm for simultaneous disparity estimation and object segmentation using the stochastic diffusion. The stochastic diffusion is a new optimization method to search for the solutions in the MAP estimation, and is formulated to perform the simultaneous correspondence estimation and object segmentation using Markov random field models. A cluster...

Object-based coding of stereo image sequences using joint 3-D motion/disparity compensation

An object-based coding scheme is proposed for the coding of a stereoscopic image sequence, using motion and disparity information. A hierarchical block-based motion estimation approach is used for initialization, while disparity estimation is performed using a pixel-based hierarchical dynamic programming algorithm. A split and merge segmentation procedure based on 3-D motion modeling is then us...

Relative Disparity Using Motion in Stereo Vision

In this paper we propose a method which uses motion in the field of view of two un-calibrated cameras to produce a disparity map relative to the cameras. Current stereo vision initialisation techniques focus on time consuming manual calibration of stereo cameras. This research demonstrates the use of a novel algorithm which uses motion to determine conjugate pairs of points. The disparity map i...
