We will apply geometric and harmonic instruments to face problems of machine vision, both for defect detection and for satellites navigation.The problems of machine vision to detect small defects, will be faced by Marposs. Problems of machine vision with the scope of satellite navigation will be faced at GMV. Here, new techniques of group-based features extraction (WP5) and geometric diffusion (WP4) will be needed for the development of more accurate trajectory estimation in spatial missions
