Multi-view Video plus Depth (MVD) data offer a reliable representation of three dimensional (3D) scenes for 3D Video applications. This is a huge amount of data whose compression is an important challenge for researchers at the current time. Consisting of texture and depth video sequences, the question of the relationship between these two types of data regarding bitrate allocation often raises...

Image Based Rendering holds a lot of promise for navigating through a real world scene without modeling it manually. Different representations have been proposed for IBR in the literature. In this paper, we argue that a representation using depth maps and texture images from a number of viewpoints is a rich and viable representation for IBR. We discuss different aspects of this representation i...

The synthesis of many textures can be simplified if they are first decomposed into simpler subtextures. Such bootstrap procedure allows to first consider a ‘label texture’, that captures the layout of the subtextures, after which the subtextures can be filled in. A companion paper focuses on this latter aspect. This paper describes an approach to arrive at the label texture. Pairwise pixel simi...

Depth image based rendering techniques for multiview applications have been recently introduced for efficient view generation at arbitrary camera positions. Encoding rate control has thus to consider both texture and depth data. Due to different structures of depth and texture images and their different roles on the rendered views, distributing the available bit budget between them however requ...

For the sake of concreteness, let’s think about the problem of estimating visual depth. A commonly assumed framework for how an observer might go about judging the depth of a visual object defined by multiple visual cues is the following two-stage process. First, depth estimates based on individual cues are derived. Next, a weighted combination of these estimates is calculated and used as the o...

Partition of unity parametrics (PUPs) are a recent framework designed for geometric modeling. We propose employing PUPs for procedural texture synthesis, taking advantage of the framework’s guarantees of high continuity and local support. Using PUPs to interpolate among data values distributed through the plane, the problem of texture synthesis can be approached from the perspective of point pl...

Meaningful facial parts can convey key cues for both facial action unit detection and expression prediction. Textured 3D face scan can provide both detailed 3D geometric shape and 2D texture appearance cues of the face which are beneficial for Facial Expression Recognition (FER). However, accurate facial parts extraction as well as their fusion are challenging tasks. In this paper, a novel syst...

For Autonomous Ground Vehicles, modelling of the terrain is important for predicting future behaviours and control options. Current terrain modelling is able to identify geometric hazards but has a limited ability to identify complex terrain characteristics. This paper presents a method for segmenting and classifying terrain types based on range data to establish a geometric model of the terrai...

soil characteristics is very important in water erosion processes. the present investigation was conducted in gully lands of ardebil province, iran, to assess the role of soil texture and structure on aggregate stability using wet sieve method. to achieve the study purposes, mean weighted diameter of aggregates was calculated, and its relationships with lime and clay percentages, sodium absorpt...

Perceived depth was measured for three-types of stereograms with the colour/texture of half-occluded (monocular) regions either similar to or dissimilar to that of binocular regions or background. In a two-panel random dot stereogram the monocular region was filled with texture either similar or different to the far panel or left blank. In unpaired background stereograms the monocular region ei...
