— Depth sensors based on projected structured light have become standard in robotics research. However, when several of these sensors share the same workspace, the measurement quality can deteriorate significantly due to interference of the projected light patterns. We present a comprehensive study of this effect in Kinect and Xtion RGB-D sensors. In(More)
— We propose a novel method for efficient object search in realistic environments. We formalize object search as a probabilistic inference problem over possible object locations. The method makes two contributions. First, we identify five priors, each capturing structure inherent to the physical world that is relevant to the search problem. Second, we(More)
We investigate how video-based recognition of rat social behavior is affected by two common tracking errors – animal misidentification and inaccurate localization of body parts. Our analyses show that correct identification is required to accurately recognize interactions. Precise local-ization of body points is beneficial for recognizing interactions that(More)
