As one of the fundamental technologies for scene understanding, semantic segmentation has been widely explored in last few years. Light field cameras encode geometric information by simultaneously recording spatial and angular light rays, which provides us with a new way to solve this issue. In paper, we propose high-quality challenging urban dataset, containing 1074 samples composed real-world...

This paper presents a system based on intelligent agents for the semantic annotation of learning resources taking into account the context of training. Semantic annotations systems rarely treat existing semantic annotations in the field of distance education (e-learning). Most researchers in the field of education limit annotations to specific cases (teacher annotation, learner annotation, anno...
