— We present a human-robot interactive scenario consisting of a memory card game between Honda's humanoid robot ASIMO and a human player. The game features perception exclusively through ASIMO's on-board cameras and both reactive and proactive behaviors specific to different situational contexts in the memory game. ASIMO is able to build a dynamic… (More)
We present a shape matching algorithm based on the chamfer distance transform which can be easily integrated into the well-known SIFT framework. The shape matching was designed to overcome the limitations of SIFT matching for objects which lack texture and have the majority of their features located on the object boundary.
Invasive species can alter the structure and functioning of ecosystems and affect the quality of the services they provide. Effects on biodiversity are well documented, but less is known about their impacts on ecosystem functioning and how these change as their populations increase. Invasive oysters, Crassostrea gigas, were added at increasing abundances to… (More)
There is a growing interest on physical and biogeochemical oceanic hindcasts and forecasts from a wide range of users and businesses. In this contribution we present an operational biogeochemical forecast system for the Portuguese and Galician oceanographic regions, where atmospheric, hydrodynamic and biogeochemical variables are integrated. The ocean model… (More)
