This paper describes a system called ComicDiary that automatically creates a personal diary in a comics style. ComicDiary is built as a subsystem of our ongoing project (C-MAP) to develop a personal guidance system for exhibition touring at museums, trade shows, academic conferences, cities, and so on. The aim of the C-MAP system is to provide users with personalized guidance according to temporal and spatial situations as well as individual interests. ComicDiary is designed as a casual tool for augmenting an individual user's memory as well as for encouraging communities of users to exchange personal memories. This paper presents the preliminary results of deploying the ComicDiary system as a digital assistant service for conference participants.
We propose an advanced visual hull technique to compensate for outliers using the reliabilities of the silhouettes. The proposed method consists of a foreground extraction technique based on the Generalized Gaussian Family model and a compensated shape-from-silhouette algorithm. They are connected by the intra-/inter-silhouette reliabilities to compensate for carving errors from defective segmentation or partial occlusion which may occur in a real environment. The 3D reconstruction process is implemented on a graphics processing unit (GPU) to accelerate the processing speed by using the huge computational power of modern graphics hardware. Experimental results show that the proposed method provides reliable silhouette information and an accurate visual hull in real environments at a very high speed on a common PC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
