Revisiting Active Perception [article]

Ruzena Bajcsy and Yiannis Aloimonos and John K. Tsotsos
2016 arXiv   pre-print
Despite the recent successes in robotics, artificial intelligence and computer vision, a complete artificial agent necessarily must include active perception.  ...  We argue that those contributions are as relevant today as they were decades ago and, with the state of modern computational tools, are poised to find new life in the robotic perception systems of the  ...  This is the essence of active perception -to set up a goal based on some current belief about the world and to put in motion the actions that may achieve it.  ...

Encoded Perception

Helena Shaskevich

Impact of action planning on spatial perception: Attention matters

Wladimir Kirsch
2015 Acta Psychologica  
This effect was neither due to an impact of motor execution on judgments (Exp. 2) nor due to characteristics of the movement cues or of certain target positions (Exp. 3, Exp. 5A).  ...  Previous research suggested that perception of spatial location is biased towards spatial goals of planned hand movements.  ...  Experiment 4 The previous results indicated changes in target's perception depending on planning a mouse movement.  ...

A Review of Testing Object-Based Environment Perception for Safe Automated Driving [article]

Michael Hoss, Maike Scholtes, Lutz Eckstein
2021 arXiv   pre-print
We focus on testing for verification and validation purposes at the interface between perception and planning, and structure our analysis along the three axes 1) test criteria and metrics, 2) test scenarios  ...  We find that the realization of safety-aware perception testing remains an open issue since challenges concerning the three testing axes and their interdependencies currently do not appear to be sufficiently  ...  Executing Scenarios as Test Cases We assume the execution of a test scenario to be an offline execution of a perception algorithm on previously recorded raw sensor data.  ...

2020 arXiv   pre-print
Deep neural networks based methods have been proved to achieve outstanding performance on object detection and classification tasks.  ...  This framework distills the temporal knowledge from a heavy neural networks based model over selected video frames (the perception of the moments) to a light-weight model.  ...  To retain high accuracy, a key frame selector decides to activate the oracle model and adapt the student over the environment.  ...
