Extended photometric analysis

by mcastelan | Jan 28, 2018

In this case, shape analysis becomes a problem of inverting Lambert’s law, i.e. the relationship between the surface normal and the light source direction causing an observed irradiance. The original ill-posed problem is known as shape-from-shading, however, when more...

Underwater Field Trials

Underwater environments present complex technical challenges in various aspects. On one hand, we need to account for the right sensing and actuation systems, which when integrated into a robotic system with appropriate technology, they can greatly facilitate the...

Color Adaptive Training for Underwater Color Restoration

by admin | Dec 8, 2017

For underwater robotics applications involving monitoring and inspection tasks, it is important to capture quality color images in real time. In the last years, there has been a great number of research that focus on the color correction or color restoration...

Autonomous Navigation for an Underwater Robot with Obstacle Avoidance

by admin | Dec 8, 2017

We have developed a behavioral approach for autonomous robotic exploration of marine habitat with collision avoidance. In particular, we are interested in exploration and continuous monitoring of coral reefs in order to diagnose disease or physical damage, while...

Statistical models of Shape and texture for face analysis

by admin | Dec 8, 2017

Statistical models of shape and texture for facial shape analysis Here, a previously built model is learnt for variations of shape and texture. These models are usually constructed by maximizing covariance (finding principal components) of either shape and texture. I...
