Abstract:
To efficiency search for an object associated with a sensed event, an information processing apparatus includes a sensor that analyzes a captured video and senses whether a predetermined event has occurred, a determining unit that determines a type of an object to be used as query information based on a type of the event in response to sensing of the event occurrence, and a generator that detects the object of the determined type from the video and generates the query information based on the detected object.
Abstract:
To provide a time synchronization information computation device capable of synchronizing the times of a plurality of cameras without the need of a special device, a time synchronization information computation method and a time synchronization information computation program. There are provided a plurality of video acquisition means 100-1 to 100-N for acquiring videos, a plurality of visual event detection means 101-1 to 101-N provided corresponding to the plurality of video acquisition means for analyzing the videos acquired by the plurality of video acquisition means 100-1 to 100-N to detect visual events, and generating visual event detection information including time information on when the visual events occur, and visual event integration means 102 for integrating the visual event detection information generated by the plurality of visual event detection means 101-1 to 101-N and synchronizing the times of the videos acquired by the plurality of video acquisition means 100-1 to 100-N.
Abstract:
An information processing apparatus (10) includes a time and space information acquisition unit (110) that acquires high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and a corresponding time slot, a possible surveillance target acquisition unit (120) that identifies a video to be analyzed from among a plurality of videos generated by capturing an image of each of a plurality of places, on the basis of the high-risk time and space information, and analyzes the identified video to acquire information of a possible surveillance target, and a target time and space identification unit (130) that identifies at least one of a spatial region where surveillance is to be conducted which is at least a portion of the spatial region or a time slot when surveillance is to be conducted, from among the spatial region and the time slot indicated by the high-risk time and space information, on the basis of the information of the possible surveillance target.
Abstract:
A video transmission apparatus (10) includes: a specified-position information acquisition unit (110) that acquires specified-position information indicating a specified position in an area to be surveilled including each imaging region corresponding to each of a plurality of imaging apparatuses; and a video transmission control unit (120) that selects at least one imaging apparatus from among the plurality of imaging apparatuses using imaging position information indicating a position or an imaging range of each of the plurality of imaging apparatuses and the specified-position information and transmits a video captured by the selected imaging apparatus to a video sharing apparatus that is to share the video.
Abstract:
A position and pose determination unit (103) is configured to determine a position and an pose of the video acquisition unit (110) in such a way that a level of hiding caused by overlapping of objects becomes low based on environmental object information indicating an environmental object including a structural object present in the monitored area and a placed object placed in the structural object, and staying characteristic information indicating a staying characteristic of the object determined depending on the environmental object. The analysis and display unit (111) is configured to perform at least one of analyzing a video captured by the video acquisition unit (103) at the position and the pose determined by the position and pose determination unit (110) and displaying the video.
Abstract:
A monitoring device and the like are provided which are capable of detecting an attribute change in a suspicious object that cannot be determined from the behavior of the object. An associating unit associates, among a plurality of objects detected from time-series image data, identical objects with one another. An attribute change detecting unit detects from the time-series image data a change in an attribute of at least one of the identical objects and an attendant item. A suspicious object detecting unit detects a suspicious object on the basis of the change in attribute.
Abstract:
An information processing apparatus (2000) detects a stationary object from video data (12). In addition, the information processing apparatus (2000) executes person detection process of detecting a person in vicinity of an object (target object) detected as the stationary object for each of a plurality of video frames (14) which includes the target object. Furthermore, the information processing apparatus (2000) executes a predetermined process by comparing results of the person detection process for each of the plurality of video frames (14).
Abstract:
In order to extract a feature suitable for comparison, the information processing device according to the present invention comprises: a prediction unit which, on the basis of the positional relationship between a plurality of objects detected and tracked in an input video and on the basis of the overlap between the plurality of objects, predicts the qualities of features extracted from the objects; a selection unit which selects, from among the plurality of objects, only those objects or that object for which the qualities of features predicted by the prediction unit satisfy a prescribed condition; and a feature extraction unit which extracts features from the objects or the object selected by the selection unit.
