In this paper, we propose an efficient multi-view video coding algorithm that uses a depth map. This algorithm is based on the correlation between texture maps and depth maps. This correlation is based on the fact that the motion vectors (MVs) in texture maps are strongly affected by their depth values. In general, background objects have smaller MVs whereas foreground objects have higher MVs. ...

As a 3D scene becomes increasingly complex and the screen resolution increases, the design of effective memory architecture is one of the most important issues for 3D rendering processors. We propose a pixel rasterization architecture, which performs a depth test operation twice, before and after texture mapping. The proposed architecture eliminates memory bandwidth waste caused by fetching unn...

In the Whitehall Forest of Georgia during the 1985-86 non-growing season soil CO, varied with soil depth, varied spatially at constant depth, and varied temporally with changing environmental conditions. Variations with depth in the upper 1.4 m of the soil were of greater magnitude than temporal variations and spatial differences at 30 cm depth were of lesser magnitude. Mean soil CO, in evergre...

OBJECTIVE To assess the safety and efficacy of ablative fractional resurfacing (AFR) for nonacne atrophic scarring. DESIGN In this before-and-after trial, each scar received 3 AFR treatments and 6 months of follow-up. SETTING Private academic practice. PATIENTS Fifteen women with Fitzpatrick skin types I to IV, aged 21 to 66 years, presented with 22 nonacne atrophic scars between June 1 a...

In this paper, a low-complexity algorithm is proposed to reduce the complexity of depth map compression in the high-efficiency video coding (HEVC)-based 3D video coding (3D-HEVC). Since the depth map and the corresponding texture video represent the same scene in a 3D video, there is a high correlation among the coding information from depth map and texture video. An experimental analysis is pe...

In this paper, we introduce a new method for depth perception from a 2D natural scene using scale variation of patterns. As the surface from a 2D scene gets farther away from us, the texture appears finer and smoother. Texture gradient is one of the monocular depth cues which can be represented by gradual scale variations of textured patterns. To extract feature vectors from textured patterns, ...

This paper introduces a new form of representation for three-dimensional video objects. We propose to provide the capability to encode depth data for video object planes, as they are used in the MPEG-4 video standard. We introduce a technique to extract depth and texture data from video objects, that are captured with multiple-camera configurations. The video object plane then represents an unw...

We present the concept of volumetric depth-peeling. The proposed method is conceived to render interior and exterior iso-surfaces for a fixed iso-value and to blend them without the need to render the volume multiple times. The main advantage of our method over pre-integrated volume rendering is the ability to extract arbitrarily many iso-layers for the given iso-value. Up to now, pre-integrate...
