We are testing these computer vision technologies in the field in real-time with low-cost platforms, with the intention of later putting these algorithms on robotic platforms for exploring the Moon and Mars. Currently working with collaborators in Madrid, Malta, St. Louis, Bielefeld and Berlin, in order to: a) Do more comprehensive field tests at sites of geological and astrobiological interest using both the uncommon-map and novelty-detection systems. b) Make the phone-cam system work with a field laptop enabled with Bluetooth, for automatic transfer of the images from the phone to the laptop and (marked- up) back to the phone. This should speed up the testing. Future:0) Improved image-segmentation (to include texture) 1) Improved Novelty Detection (better statistical measures) 2) Improved cameras (hyperspectral cameras) 3) Improve technological readiness for planetary robotics missions.
