Advancements in Virtual Reality have enabled well-defined and consistent virtual environments that can capture complex scenarios, such as human everyday activities. Additionally, virtual simulators (such as SIGVerse) are designed to be user-friendly mechanisms between virtual robots/agents and real users allowing a better interaction. We envision such rich scenarios can be used to train robots to...
Automatically segmenting and recognizing human activities from observations typically requires a very complex and sophisticated perception algorithm. Such systems would be unlikely implemented on-line into a physical system, such as a robot, due to the pre-processing step(s) that those vision systems usually demand. In this work, we present and demonstrate that with an appropriate semantic representation...
In this paper, we present a two-stage framework that deal with the problem of automatically extract human activities from videos. First, for action recognition we employ an unsupervised state-of-the-art learning algorithm based on Independent Subspace Analysis (ISA). This learning algorithm extracts spatio-temporal features directly from video data and it is computationally more efficient and robust...
