    Picture models for 2-scene comics creating system

    Full text link
    Recently, computer understanding pictures and stories becomes one of the most important research topics in computer science. However, there are few researches about human like understanding by computers because pictures have not certain format and contain more lyric aspect than that of natural laguage. For picture understanding, a comic is the suitable target because it is consisted by clear and simple plot of stories and separated scenes.In this paper, we propose 2 different types of picture models for 2-scene comics creating system. We also show the method of the application of 2-scene comics creating system by means of proposed picture model

    Picture information shared conversation agent: Pictgent

    Full text link
    Recently, the various dialogue systems have been proposed to make a natural conversation with users. In this paper, we propose a novel dialogue system called Pictgent which utilizes "pictures" with model of situation in order to share common knowledge between users and the system. We show the basic concept and system structure of proposed Pictgent. Statistical experiments are carried out in order to confirm the effectiveness of Pictgent..</div

    Stippling Data on Backgrounds of Pages - Toward Seamless Integration of Paper and Electronic Documents

    Full text link
    In order to realize seamless integration of paper and electronic documents, it is at least necessary to assure error free conversion from one to the other. In general, the conversion from paper to electronic documents is the task of document image understanding. Although its research has made remarkable progress, it is still a hard task without limiting the type of documents. This paper presents a completely different approach to this task on condition that printed documents have their originals in electronic form. The proposed method employs fine dots to represent data of electronic documents and places the dots on white space (backgrounds) of pages. Since the data is encoded with an error correcting code, it is guaranteed to be correctly recovered from the scanned images of documents. Experimental results show that a page with normal foreground objects (characters and other things) can contain more than 4KB of data, even when errors up to 20% of the data are permitted. 1

    Therapeutic potential of dedifferentiated fat cells in a rat model of osteoarthritis of the knee

    Introduction: Mature adipocyte-derived dedifferentiated fat cells (DFATs) represent a subtype of multipotent cells that exhibit comparable phenotypic and functional characteristics to adipose-derived stem cells (ASCs). In this study, we assessed the chondroprotective properties of intra-articularly administrated DFATs in a rat model of osteoarthritis (OA). We also investigated in vitro the expression of anti-inflammatory and chondroprotective genes in DFATs prepared from the infrapatellar fat pad (IFP) and subcutaneous adipose-tissue (SC) of human origin. Methods: In the cell transplantation experiment, rats were assigned to the DFAT and Control group (n = 10 in each group) and underwent anterior cruciate ligament transection (ACLT) accompanied by medial meniscus resection (MMx) to induce OA. One week later, they received intra-articular injections of 1 × 106 DFATs (DFAT group) or PBS (control group) four times, with a weekly administration frequency. Macroscopic and microscopic evaluations were conducted five weeks post-surgery. In the in vitro experiments. DFATs derived from the IFP (IFP-DFATs) and SC (SC-DFATs) were prepared from donor-matched tissue samples (n = 3). The gene expression of PTGS2, TNFAIP6, PRG4, BMP2, and BMP6 under TNF-α or IFN-γ stimulation in these cells was evaluated using RT-PCR. Furthermore, the effect of co-culturing synovial fibroblasts with DFATs on the gene expression of ADAMTS4 and IL-6 were evaluated. Results: Intra-articular injections of DFATs significantly inhibited cartilage degeneration in the rat OA model induced by ACLT and MMx. RT-PCR analysis revealed that both IFP-DFATs and SC-DFATs upregulated the expression of genes involved in immune regulation, anti-inflammation, and cartilage protection such as PTGS2, TNFAIP6, and BMP2, under stimulation by inflammatory cytokines. Co-culture with DFATs suppressed the expression of ADAMTS4 and IL6 in synovial fibroblasts. Conclusions: The intra-articular injection of DFATs resulted in chondroprotective effects in the rat OA model. Both SC-DFATs and IFP-DFATs induced the expression of anti-inflammatory and chondroprotective genes in vitro. These results indicate that DFATs appear to possess therapeutic potential in inhibiting cartilage degradation and could serve as a promising cellular resource for OA treatment
