— We describe a probabilistic framework for detection and modeling of doors from sensor data acquired in corridor environments with mobile robots. The framework captures shape, color, and motion properties of door and wall objects. The probabilistic model is optimized with a version of the expectation maximization algorithm, which segments the environment(More)
BACKGROUND Individuals with inactive alleles of the fucosyltransferase 2 gene (FUT2; termed the 'secretor' gene) are common in many populations. Some members of the genus Bifidobacterium, common infant gut commensals, are known to consume 2'-fucosylated glycans found in the breast milk of secretor mothers. We investigated the effects of maternal secretor(More)
JavaScript is not typically associated with high performance rendering. This talk covers techniques that were used to bring the massive data set of Google Earth into a web browser using standard JavaScript and WebGL. The client has access to a 3d model of the entire world, an ever-growing data set stored in servers, and the client needs to fetch and(More)
Since its inception, Google Earth has been brought to a variety of platforms: from desktop to mobile devices, from native to web. This talk discusses bringing Google Earth to virtual reality, a platform that poses unique challenges in user interaction and rendering. We present solutions to help users navigate planet-sized worlds in VR without losing context(More)
