Current and near-term visual prostheses are severely limited in their capacity to convey visual information about the scene to implantees. This has motivated consideration of how vision processing algorithms can be designed and used to maximise the bandwidth available, in order to improve functional outcomes for patients. In this talk the speaker will present an overview of recent and ongoing work at NICTA CRL towards the development of computer vision algorithms and novel visual representations to enhance the perception of scene structure in prosthetic vision. In particular, the presentation will outline recent work demonstrating how such algorithms may be used to emphasise low contrast ground obstacles, and encode the time-to-contact of objects posing an imminent threat of collision. Obstacle avoidance work has been shown to reduce collisions by close to 50% compared with non-augmented visual representations in mobility trials with simulated prosthetic vision.
