This paper introduces a novel method for capturing conversation scenes and editing of the obtained videos. This system aims to acquire high-quality videos and to utilize them for multimedia that provides conversation functions. First, a video capturing system composed of " environmental camera module " and " contents capturing camera modules " is(More)
Transforming growth factor β (TGFβ) derived from the tumor microenvironment induces malignant phenotypes such as epithelial-mesenchymal transition (EMT) and aberrant cell motility in lung cancers. TGFβ-induced translocation of β-catenin from E-cadherin complexes into the cytoplasm is involved in the transcription of EMT target genes. PTEN (phosphatase and(More)
Transforming growth factor β (TGFβ) causes the acquisition of epithelial-mesenchymal transition (EMT). Although the tumor suppressor gene PTEN (phosphatase and tensin homologue deleted from chromosome 10) can negatively regulate many signaling pathways activated by TGFβ, hyperactivation of these signaling pathways is observed in lung cancer cells. We(More)
This paper introduces video quality analysis for automated video capture and editing. Previously, we proposed an automated video capture and editing system for conversation scenes. In the capture phase, our system not only produces concurrent video streams with multiple pan-tilt-zoom cameras but also recognizes " conversation states " i.e., who is speaking,(More)
