A fundamental problem in processing sequences of images is the computation of optic ow, an approximation of the motion eld which is the projection of velocities of 3-d surface points onto the imaging plane of a visual sensor. A wide variety of algorithms for computing optical ow has been reported in the literature. However, it is not until recently that multiple motion paradigms were seriously ...

A new method for solving the stereo matching problem in the presence of large occlusion is presented. A data structure | the disparity space image | is deened in which we explicitly model the eeects of occlusion regions on the stereo solution. We develop a dynamic programming algorithm that nds matches and occlusions simultaneously. We show that while some cost must be assigned to unmatched pix...

purpose: to compare repeated intravitreal injections of bevacizumab (ivb) with triamcinolone acetonide (ivt) for treatment of acute branch retinal vein occlusion (brvo). methods: this randomized clinical trial included, 86 eyes with recent onset (less than 12 weeks) brvo. participants were randomly assigned to two treatment groups: the ivb group (43 eyes) consisted of patients who received mont...

A highly reliable model for the study of focal cerebral ischemia has been developed using a retro-orbital approach to occlude the lateral lenticulostriate arteries of the baboon. An infarction of the caudate, putamen and the anterior limb of the internal capsule has consistently been produced. Reliability has been attained because the anatomical variations of the lenticulostriate arteries of ea...

1 We present Neural Network Ambient Occlusion (NNAO), a fast, ac2 curate screen space ambient occlusion algorithm that uses a neural 3 network to learn an optimal approximation of the ambient occlu4 sion effect. Our network is carefully designed such that it can be 5 computed in a single pass allowing it to be used as a drop-in re6 placement for existing screen space ambient occlusion technique...

Self motion perception involves the integration of visual, vestibular, somatosensory and motor signals. This article reviews the findings from single unit electrophysiology, functional and structural magnetic resonance imaging and psychophysics to present an update on how the human and nonhuman primate brain integrates multisensory information to estimate one’s position and motion in space. The...
