Patent number: 12073613Abstract: Described is a system for adapting to perception errors in object detection and recognition. The system receives, with a perception module, perception data from an environment proximate a mobile platform that reflects objects in the environment. Perception probes representing perception characteristics of object detections are generated from the perception data. Using the perception probes, spatial logic-based constraints and temporal logic-based constraints are generated. Spatial perception parameters are determined by solving an optimization problem using a set of the spatial logic-based constraints. Temporal perception parameters are determined by solving an optimization problem using a set of temporal logic-based constraints. The spatial perception parameters and the temporal perception parameters are combined to estimate a final perception parameter. The perception module is adjusted based on the final perception parameter.Type: GrantFiled: May 12, 2022Date of Patent: August 27, 2024Assignee: HRL LABORATORIES, LLCInventors: Hyukseong Kwon, Alexie Pogue, Kevin Lee, Amir M.

Patent number: 11941870Abstract: Described is a system for action recognition error detection and correction using probabilistic signal temporal logic. The system is initiated by training an action recognition system to generate true positive (TP)/false positive (FP) axioms. Thereafter, the system ca be used to classify one or more actions in a video sequence as true action classifications by using the TP/FP axioms to remove false action classifications. With the remaining true classifications, a device can be controlled given the situation and relevant true classification.Type: GrantFiled: March 18, 2022Date of Patent: March 26, 2024Assignee: HRL LABORATORIES, LLCInventors: Hyukseong Kwon, Amit Agarwal, Kevin Lee, Amir M.

Patent number: 11854252Abstract: Described is a system for evaluating and correcting perception errors in object detection and recognition. The system receives perception data from an environment proximate a mobile platform. Perception probes are generated from the perception data which describe perception characteristics of object detections in the perception data. For each perception probe, probabilistic distributions for true positive and false positive values are determined, resulting in true positive and false negative perception probes. Statistical characteristics of true positive perception probes and false positive perception probes are then determined. Based on the statistical characteristics, true positive perception probes are clustered. An axiom is generated to determine statistical constraints for perception validity for each perception probe cluster. The axiom is evaluated to classify the perception probes as valid or erroneous. Optimal perception parameters are generated by solving an optimization problem based on the axiom.Type: GrantFiled: March 22, 2022Date of Patent: December 26, 2023Assignee: HRL LABORATORIES, LLCInventors: Hyukseong Kwon, Amit Agarwal, Amir M.

Patent number: 11694120Abstract: Described is a system for detecting and correcting perception errors in a perception system. In operation, the system generates a list of detected objects from perception data of a scene, which allows for the generation of a list of background classes from backgrounds in the perception data associated with the list of detected objects. For each detected object in the list of detected objects, a closest background class is identified from the list of background classes. Vectors can then be used to determine a semantic feature, which is used to identify axioms. An optimal perception parameter is then generated, which is used to adjust perception parameters in the perception system to minimize perception errors.Type: GrantFiled: March 2, 2021Date of Patent: July 4, 2023Assignee: HRL LABORATORIES, LLCInventors: Amit Agarwal, Amir M.

Patent number: 11350039Abstract: Described is a system for contrast and entropy-based perception adaption to optimize perception. The system is operable for receiving an input image of a scene with a camera system and detecting one or more objects (having perception data) in the input image. The perception data of the one or more objects is converted into probes, which are then converted into axioms using probabilistic signal temporal logic. The axioms are evaluated based on probe bounds. If the axioms are within the probe bounds, then results are provided; however, if the axioms are outside of the probe bounds, the system estimates optimal contrast bounds and entropy bounds as perception parameters. The contrast and entropy in the camera system are then adjusted based on the perception parameters.Type: GrantFiled: December 23, 2020Date of Patent: May 31, 2022Assignee: HRL Laboratories, LLCInventors: Hyukseong Kwon, Amir M.

Patent number: 11288498Abstract: Described is a system for learning actions for image-based action recognition in an autonomous vehicle. The system separates a set of labeled action image data from a source domain into components. The components are mapped onto a set of action patterns, thereby creating a dictionary of action patterns. For each action in the set of labeled action data, a mapping is learned from the action pattern representing the action onto a class label for the action. The system then maps a set of new unlabeled target action image data onto a shared embedding feature space in which action patterns can be discriminated. For each target action in the set of new unlabeled target action image data, a class label for the target action is identified. Based on the identified class label, the autonomous vehicle is caused to perform a vehicle maneuver corresponding to the identified class label.Type: GrantFiled: July 16, 2020Date of Patent: March 29, 2022Assignee: HRL Laboratories, LLCInventors: Amir M.
