Abstract: Systems and methods for processing surveillance video streams using image classification and object detection are described. Video data from a video image sensor may be processed using an image classifier to determine whether an object type is present in a video frame. If the object type is present, the video frame and/or subsequent video frames may be processed using an object detector to provide additional object data, such as position information, for use in other video surveillance processes. In some examples, an event message may be generated and sent to a video surveillance application in response to selective object detection.

Abstract: An autonomous mobile device (AMD) that interacts with a user operates more effectively with reliable information about that user's pose. Occlusion due to obstacles or sensor field-of-view limits may prevent a sensor from “seeing” a user's torso or lower body while the face may remain visible. Face orientation alone produces unreliable results because a user frequently moves their head. Sensor data is acquired over time and used to determine face and body poses, with each pose representing a location and orientation in physical space of that portion of the user. A transform is determined that represents the relative arrangement of a face pose and a body pose at a particular time. If available, the body pose may be used as the user's pose. If the body pose is unavailable or unreliable at a given time, it may be inferred by applying the previously determined transform to the current face pose.

Abstract: Methods for improving multiple signal reception using receiver diversity in the context of a wideband radar and communications receiver. The method allows for improved signal reception as well as improved angle of arrival estimation. A first approach uses a method that improves angle of arrival estimation while using the standard diversity technique of selection combining. A second approach uses a method of equalization of the signal rather than equalization of the channel to both improve the signal SNR over standard selection combining and further improve the angle of arrival estimate over the first approach.
