A method of controlling an image acquisition device for tracking a target object includes: detecting an event in which tracking of a first object, which is a tracking target object, fails in a first image acquired by the image acquisition device; determining, in the first image, a reference object which is used as a reference for controlling the image acquisition device; controlling the image acquisition device such that at least one of an image capturing range and an image capturing direction of the image acquisition device is adjusted based on at least one of a size and a location of the reference object in the first image; and recognizing the first object in a second image acquired by the image acquisition device in a state in which at least one of the image capturing range and the image capturing direction is adjusted.

An information processing system for obtaining an audio content file for video data providing video content representing a sport event, including: a receiver configured to receive a data stream including the video data; a preference data obtainer configured to obtain preference data, wherein the preference data indicate a selected competitor participating in the sport event; a category identifier obtainer configured to obtain a category identifier from a machine learning algorithm into which the video data is input, wherein the machine learning algorithm is trained to classify a scene represented in the video content into a category of a predetermined set of categories associated with the sport event, wherein the category identifier indicates the category into which the scene is classified; an audio content file obtainer configured to obtain, based on the obtained category identifier and the obtained preference data, the audio content file from a prestored set of audio content files, wherein the audio content file provides audio content associated with the category of the scene and the preference data; and a synchronizer configured to synchronize the audio content and the video content for synchronized play back of the scene by a media player configured to play back the video content and the audio content file.

Systems, methods and non-transitory computer readable media for analyzing objects data to generate a textual content reporting events are provided. An indication of an event may be received. An indication of a group of one or more objects associated with the event may be received. For each object of the group of one or more objects, data associated with the object may be received. The data associated with the group of one or more objects may be analyzed to select an adjective. A particular description of the event may be generated. The particular description may be based on the group of one or more objects. The particular description may include the selected adjective. A textual content may be generated. The textual content may include the particular description. The generated textual content may be provided.

Implementations generally perform robust multi-view multi-target action recognition using reconstructed 3-dimensional (3D) poses. In some implementations, a method includes obtaining a plurality of videos of a plurality of subjects in an environment, where at least one target subject of the plurality of subjects performs one or more actions in the environment. The method further includes tracking the at least one target subject across at least two cameras. The method further includes reconstructing a 3-dimensional (3D) model of the at least one target subject based on the plurality of videos and the tracking of the at least one target subject. The method further includes recognizing the one or more actions of the at least one target subject based on the reconstructing of the 3D model.

A system, method, and apparatus for implementing workflows across multiple differing systems and devices is provided herein. During operation, a workflow is automatically generated based upon a high probability of overloading resources with a current workflow. In particular, a workstation (or server) detects a high probability that a resource will be overloaded if a particular trigger is implemented. The workstation (or server) then determines an alternate trigger to reduce the chances that a resource will be overloaded. The alternate trigger and action can then be implemented or suggested as a newly-created workflow.

A system, method, and apparatus for implementing workflows across multiple differing systems and devices are provided herein. During operation a workflow is automatically generated upon the detection of new signage. In particular, a workflow server will detect the presence of new signage in a particular area. The new signage will be analyzed, and an appropriate trigger and action will be determined based on the new signage. The appropriate trigger and action will then be implemented as a newly-created workflow.

A method for optimizing a process of displaying video streams with specified event receives video streams. The video streams are sequenced based on a specified arrangement role to from a video stream queue. By analyzing each video streams, whether each video stream includes a specified event is determined. If each video stream without the specified event, the video streams are outputted based on the video stream queue. If the video stream includes the specified event, the video stream with the specified event is adjusted to be priority in the video stream queue, and the video streams are outputted based on the updated video stream queue. The video streams with the specified event can be prioritized processed and focus. A video stream processing apparatus and a computer readable storage medium applying the method are also provided.

Methods, systems, and media for adaptive presentation of a video content item based on an area of interest are provided. In some embodiments, the method comprises: causing a video content item to be presented within a viewport having first dimensions in connection with a web page, wherein the video content item is associated with area of interest information corresponding to one or more frames of the video content item; determining that the first dimensions associated with the viewport have changed in which the viewport is currently associated with second dimensions; determining that a modified video content item should be presented within the viewport having the second dimensions in response to determining that the first dimensions associated with the viewport have changed, wherein the modified video content item includes an area of interest based on the area of interest information associated with the video content item and wherein portions of at least one frame of the modified video content item are removed based on the second dimensions of the viewport; and causing the modified video content item to be presented within the viewport having the second dimensions.

A drive recorder according to an embodiment of the present disclosure includes: an imaging unit that is mounted on a vehicle and captures a video of the surroundings of the vehicle; a video recording unit that has, recorded therein, video data captured; a network connecting unit that receives accident information including a time and date when an accident occurred and a place where the accident occurred; and a video retrieving unit that determines whether any video data captured in a predetermined time period and in a predetermined region are available in the video data recorded in the video recording unit, the predetermined time period including the time and date when the accident occurred, the predetermined region including the place where the accident occurred.

System and method for detection of pre-drowning and drowning events based on underwater images are disclosed.
