A system may receive video information. The system may select a combination of light-weight features and heavy weight features. The light-weight features may be extracted from the video information and the heavy weight features not extracted. The system may forecast, based on the light-weight features and the heavy weight features, accuracy, and latency metrics for performing the object detection and tracking using a plurality of candidate branch configurations, respectively. The system may select a branch configuration from the plurality of candidate branch configurations in response to satisfaction of an optimization criterion. The system may perform object detection and tracking based on the selected branch configuration.

System for content aware reconfiguration of video object detection

System and methods for content- and contention-aware object detection are provided. A system may receive video information and perform object detection and object tracking based on an execution configuration. The system may approximate an optimized execution configuration. To approximate the optimized execution configuration, the system may identify, based on the video information, a plurality of content features. The system may further measure a contention level of a computer resource or multiple resources. The system may approximate, based on the content features and the utilization metric, latency metrics, for a plurality of execution configuration sets, respectively. The system may also approximate, based on the content features, accuracy metrics for the execution configuration sets, respectively. The system may select the optimized execution configuration set in response to satisfaction of a performance criterion. The system may perform object detection and object tracking based on the optimized execution configuration set.

System and methods for content and contention-aware approximate object detection

Techniques are disclosed for improving media content effectiveness. A methodology implementing the techniques according to an embodiment includes generating an intermediate representation (IR) of provided media content, the IR specifying editable elements of the content and maintaining a result of cumulative edits to those elements. The method also includes editing the elements of the IR to generate a set of candidate IR variations. The method further includes creating a set of candidate media contents based on the candidate IR variations, evaluating the candidate media contents to generate effectiveness scores, and pruning the set of candidate IR variations to retain a threshold number of the candidate IR variations as surviving IR variations associated with the highest effectiveness scores. The process iterates until either an effectiveness score exceeds a threshold value, the incremental improvement at each iteration falls below a desired value, or a maximum number of iterations have been performed.
