Abstract: Arrangements described herein relate to apparatuses, systems, and methods for a housing of an unmanned aerial vehicle (UAV), the housing includes but is not limited to a metallic porous material having a shape of an enclosure of the UAV, and a phase change material (PCM) provided in at least a portion of the metallic porous material. The metallic porous material and the PCM are configured to passively cool the UAV.

Abstract: To determine real-world information about objects moving in a scene, the camera capturing the scene is typically calibrated to the scene. Automatic scene calibration can be accomplished using people that are found moving about in the scene. During a calibration period, a video content analysis system processing video frames from a camera can identify blobs that are associated with people. Using an estimated height of a typical person, the video content analysis system can use the location of the person's head and feet to determine a mapping between the person's location in the 2-D video frame and the person's location in the 3-D real world. This mapping can be used to determine a cost for estimated extrinsic parameters for the camera. Using a hierarchical global estimation mechanism, the video content analysis system can determine the estimated extrinsic parameters with the lowest cost.

Abstract: Techniques and systems are provided for processing video data. For example, techniques and systems are provided for performing content-adaptive object or blob tracking. To perform the content-adaptive object tracking, a blob tracker is associated with a blob generated for a video frame. The blob includes pixels of at least a portion of a foreground object in a video frame. A size of the blob can be determined to be greater than a blob size threshold. The blob tracker can be converted to a normal tracker based on the size of the blob being greater than the size threshold. The associated blob tracker and blob are output as an identified blob tracker-blob pair when the blob tracker is converted to the normal tracker.
