Inaccurate depth map discontinuities are an important source of artifact and distortion in multiview systems and applications requiring depth-based view rendering such as 3DTV or free-viewpoint video. Such errors along depth discontinuities frequently occur during depth estimation and/or depth map coding. In this paper we present a novel method for correcting inaccuracies on the discontinuities...

In this contribution a novel stereo matching technique for depth estimation in stereoscopic image pairs is pre sented The input image pair is preprocessed in the in tensity domain and edge maps together with an adap tive mesh approximating to linearly modeled regions are obtained Then an iterative stripe based quadri lateral patch matching technique is employed to esti mate the depth map from t...

this research was carried out based on systematic analysis approach for evaluation of ecological resources capability of kasilian representative catchment for agricultural land use. the study area is located in southern of mazandaran province. in this study we used topography digital data, paper maps, climatology data, satellite images and gis, database and spreadsheet software. the process of ...

With increasing demands of 3D contents, conversion of many existing two-dimensional contents to three-dimensional contents has gained wide interest in 3D image processing. It is important to estimate the relative depth map in a singleview image for the 2D-To-3D conversion technique. In this paper, we propose an automatic conversion method that estimates the depth information of a single-view im...

To investigate pedological criterion on land degradation in Quaternary rock units, at first, a part of the shoor watershed area was selected. After distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. In this research three indices of erodibility, salinity and permeability of soils were considere...

In this paper, we present a new system to generate multiview video sequences with depth information (MVD) by integrating multiple high-definition (HD) camera arrays and one standard-definition (SD) depth camera. In the proposed hybrid camera system, we first create the initial disparity for each HD color image by applying a threedimensional (3-D) warping operation on the depth map acquired by t...

bazargan and poldasht plains are located in the north of west azarbaijan, northwest of iran. in this area, groundwater supplies main water demands. aim of this research is assessment of aquifer vulnerability for contamination potential on the basis of hydrogeological conditions of the study area. for this purpose the combined use of the drastic and geographical information system (gis) demonstr...

BACKGROUND Rye (Secale cereale L.) is an economically important crop, exhibiting unique features such as outstanding resistance to biotic and abiotic stresses and high nutrient use efficiency. This species presents a challenge to geneticists and breeders due to its large genome containing a high proportion of repetitive sequences, self incompatibility, severe inbreeding depression and tissue cu...
