Stereo positioning is a important content for Spaceborne SAR imagery mapping, which is still lack of investigation depend on exterior orientation elements. In this paper, we firstly introduced the Range-Coplanarity (R-Cp) geometric imaging equation and its character for radar imagery, compared the difference and relationship between R-Cp and R-D model, and build stereo positioning rigorous mode...

The crosstalk is always an issue for 3D displays, a digital image processing methods we proposed.optical crosstalk in 3D displays that could further reduce. MZ-DCR method is not only based on the software approach,but pixel structure also using 3D displays. 3D display with 2DIG panel was used to demonstrate a improvement of MZ-DCR method.

The dense stereo disparity map, i.e. image based distance measurement has been developed for applications such as robotic vision and video surveillance. Two small video cameras embedded in the hand-held computer or game controller can be turned into a distance image sensor or a range finder. Electrical retina stimulation with the implanted 2D electrode array that has recently been reported is p...

Stereo vision is fast becoming a highly investigated area in the domain of image processing. Depth information may be obtained from stereo or multi-vision images for reconstructing objects in 3D based on 2D information. Robotic applications make use of stereo vision for navigation purposes, locking down targets, as well as simulating human-like behaviour. This paper presents an algorithm for th...

Stereo vision deals with images acquired by a stereo camera setup, where the disparity between the stereo images allows depth estimation within a scene. 3D information, hence, is retrieved which is essential in many machine vision applications. Disparity map extraction of an image is a computationally demanding task. Previous work on disparity map computation is mainly limited to software based...

This paper presents the method for detecting pedestrian recently implemented on the ARGO vehicle. The perception of the environment is performed through the sole processing of images acquired from a vision system installed on board of the vehicle: the analysis of a monocular image delivers a first coarse detection, while a distance refinement is performed thanks to a stereo vision technique.

Stereo-correspondence is the most important issue in stereopsis. Feature extraction and matching are the basic steps involved in the solution of stereocorrespondence problem. This work examines the effectiveness of Gabor Logons as pre-processing technique compared to intensity image. The matching is performed using Hopfield network and Simulated Annealing. Performance of these matching techniqu...

This paper presents a quantitative evaluation of a set of approaches for increasing the accuracy of an area-based stereo matching method. It is targeting real-time FPGA systems focused on low resource usage and maximized improvement per cost unit to enable concurrent processing. The approaches are applied to a resource optimized correspondence implementation and the individual and cumulative co...

In this article a method for reconstructing atmospheric cloud surfaces using a stereo camera system is presented. The proposed camera system utilizes fish-eye lenses in a flexible wide baseline camera setup. The entire workflow from the camera calibration to the creation of the 3D point set is discussed, but the focus is mainly on cloud segmentation and on the image processing steps of stereo r...

hyperion hyperspectral data contains a very rich source of information from the earth surface that collects 242 narrow contiguous spectral bands. achieving this source of rich information is subject to the performance of suitable image processing methods on raw satellite data. satellite image processing methods can be classified into two categories of statistical-based and spectral-based. in th...
