This study explored the feasibility of localized manganese-enhanced MRI (MEMRI) via 3 different routes of Mn administrations for visuotopic brain mapping of retinal, callosal, cortico-subcortical, transsynaptic and horizontal connections in normal adult rats. Upon fractionated intravitreal Mn injection, Mn enhancements were observed in the contralateral superior colliculus (SC) and lateral geni...

Multiview video in “texture-plus-depth” format enables decoder to synthesize freely chosen intermediate views for enhanced visual experience. Nevertheless, transmission of multiple texture and depth maps over bandwidthconstrained and loss-prone networks is challenging, especially for conferencing applications with stringent deadlines. In this paper, we examine the problem of loss-resilient codi...

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...

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 ...
