Following another person's gaze in order to achieve joint attention is an important skill in human social interactions. This work analyzes geometric aspects of the gaze following problem and proposes a learning-based computational model for the emergence of gaze following skills in infants. The model acquires advanced gaze following skills by learning associations between caregiver head poses a...

Depth-image-based rendering (DIBR) is a method to represent a stereoscopic content. The DIBR consists of a monoscopic center view and an associated per-pixel depth map. Using these two components and given depth condition from a user, the DIBR renders left and right views. The advantages of DIBR are numerous. The user can choose not only the monoscopic or stereoscopic view selectively, but also...

In this paper, we propose a method to extract depth from motion, texture and intensity. We first analyze the depth map to extract a set of depth cues. Then, based on these depth cues, we process the colored reference video, using texture, motion, luminance and chrominance content, to extract the depth map. The processing of each channel in the Y CRCB−color space is conducted separately. We test...

in order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. physical and chemical properties of soil are effective in distribution of plant species in local area. to determine the effects of some soil properties on species distribution of eurotia ceratoides and stipa barbata in baghedar summer region of bafgh, three ...

   Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...

With the introduction of the original Radeon the general rendering performance landscape changed significantly due to the revolutionary technology that is HyperZ. Today this technology has been upgraded, fine-tuned and improved in several generations and is now a general commodity that everyone expects to have. Yet it is sometimes not well understood or taken proper advantage of. Developing 3D ...

plant performance and freshness is related to the pattern of its root growth development, which is highly affected by the water amount and water use management. therefore, the spatiotemporal variation of maize root under five treatments including full irrigation treatment (fi), partial root-zone drying treatments at two levels (receiving 75% of et =prd75, and 55% of et= prd55) and deficit irrig...

Generalised halfspace depth function is proposed. Basic properties of this depth function including the strong consistency are studied. We show, on several examples that our depth function may be considered to be more appropriate for nonsymetric distributions or for mixtures of distributions.
