Abstract: A system may track a person at a location across multiple cameras in real time, while maintaining identification of the person through their visit. The person may not be personally identified; however, the person's presence in video frames captured by different cameras may be linked together. The linked frames may be evaluated by one or more analytics applications. For example, an analytics application may determine a trajectory of a person through a location and plot an overlay of that person's trip through the location on the map. This information may be used, for example, to optimize store layout, asset protection purposes, for counting a number of people at the location at a given time (e.g., for understanding busy hours of the location), determining whether social distancing or other health and/or safety measures may be in compliance, etc.

Abstract: A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

Abstract: Systems and methods are described herein for displaying subjects of a portion of content and searching for content related to a particular subject in the content. Media data of content is analyzed during playback, and a number of action signatures are identified. Each action signature is associated with a particular subject within the content. The action signature is stored, along with a timestamp corresponding to a playback position at which the action signature begins, in association with an identifier of the particular subject. Upon receiving a command, icons representing each of a number of action signatures at or near the current playback position are displayed. Upon receiving user selection of an icon corresponding to a particular signature, a portion of the content corresponding to the action signature is played back or a search interface is displayed including autocomplete suggestions related to the subject of the signature.

Abstract: In a method, whether a sequence of pictures includes a flash picture is determined. The flash picture is associated with a scene change between (i) a first scene of a picture of the sequence of pictures and (ii) a second scene of a prior picture and a subsequent picture of the picture in the sequence of pictures. The scene change is determined based on a content change between the first scene and the second scene being larger than a threshold. An encoding process is performed on a current picture in the sequence of pictures in response to (i) the picture being determined as the flash picture and (ii) the picture being the current picture.

The instructions also cause the processor to use the boom position data and a 3D model of the boom to project a digital representation of the boom into the image space. The processor then minimizes a difference between the projected and real images of the boom to thereby calibrate the camera.
