4SkeletonFeat: A Framework for Unifying the Extraction of Features from Videos of Human Activities
Resumo
Neste artigo, é proposto um framework para unificar a extração de características de vídeos de atividades humanas. O framework, chamado 4SkeletonFeat, fornece um conjunto de ferramentas e bibliotecas que permitem aos pesquisadores extrair facilmente características de vídeos de atividades humanas. Ele permite extrair características como: ”Joint”, ”Bone”, ”Bone-Motion” e ”Joint-Motion” de vídeos de atividades humanas. Este framework também fornece um conjunto de ferramentas para representação dessas características, como representações baseadas em tokens, representações baseadas em grafos, representações pseudo-imagem e representações baseadas em sequência. Para avaliar o framework proposto, um novo conjunto de dados chamado FitTube foi desenvolvido a partir de vídeos do Youtube. Os resultados mostram que 4SkeletonFeat é capaz de extrair características de vídeos de atividades humanas e fornecer uma boa representação para essas características para tarefas de Aprendizado de Máquina.
