Abstract: Apparatuses, systems, and techniques for dynamically composable object tracker configuration for intelligent video analytics systems. A state of one or more objects included in an object is tracked using an object tracking application that implements an object tracker of a first type based on images depicting the environment. A request is received to perform tracking using a second object tracker type that is different from the first object tracker type. The object tracking application is configured to implement an object tracker of the second object tracker type in accordance with the request. The state of the objects in the environment is tracked using the object tracking application that implements the object tracker of the second object tracker type based on the images depicting the environment.

Abstract: Apparatuses, systems, and techniques for real-time persistent object tracking for intelligent video analytics systems. A state of a first object included in an environment may be tracked based on a first set of images depicting the environment. The first set of images may be generated during a first time period. It may be determined that the first object is not detected in the environment depicted in a second set of images. The second set of images may be generated during a second time period that is subsequent to the first time period. One or more predicted future states of the first object may be obtained in view of the state of the first object in the environment depicted in the first set of images. A second object may be detected in the environment depicted in a third set of images generated during a third time period that is subsequent to the second time period. A determination may be made as to whether a current state of the second object corresponds to at least one of the one or more predicted future states of the first object. In response to a determination that a current state of the second object corresponds to at least one of the predicted future states of the first object, an identifier associated with the second object is updated to correspond to an identifier associated with the first object.

Abstract: Apparatuses, systems, and techniques for real-time persistent object tracking for intelligent video analytics systems are provided. A first object is tracked in an environment depicted by a first set of images. One or more predicted future states of the first object in the environment are obtained. A second object is detected in the environment depicted by a second set of images. A number of images of the second set of images exceeds a threshold number of images. A determination is made of whether a current state of the second object corresponds to at least one of the predicted future states of the first object. Responsive to a determination that a current state of the second object corresponds to at least one of the predicted future states of the first object, state data for the first object is updated based on the determined current state of the second object.

Abstract: A first visual appearance descriptor associated with a first object in an environment is obtained based on a first set of images of a first time period. The first object is subsequently absent from the environment in a second set of images of a second time period. A second visual appearance descriptor associated with a second object is obtained based on a third set of images, of a third time period subsequent to the second time period. A compound similarity metric between the first and second objects is obtained in view of visual appearance similarity and motion similarity metrics. The visual appearance similarity metric corresponds to a degree of similarity between the first and second visual appearance descriptors. An identifier associated with the second object is updated to correspond to an identifier associated with the first object in response to determining that the compound similarity metric meets a threshold value.

Abstract: Apparatuses, systems, and techniques for managing lost objects in an intelligent video analytics system. A first set of application modules is executed for an object tracking application configured to track, based on images depicting an environment, a state of objects included in the environment. The first set of application modules is associated with a first object tracker type. A request is received to configure the object tracking application to execute a second set of application modules associated with a second object tracker type. The second set of application modules includes one or more application modules that are different from application modules of the first set of application modules. The object tracking application is configured to execute the second set of application modules in accordance with the request. The second set of application modules is executed for the object tracking application to track, based on the images depicting the environment, the state of the objects included in the environment.
