We propose a novel formulation to express the attachment of a polygonal surface to a skeleton using purely linear terms. This enables to simultaneously adapt the pose and shape of an articulated model in an efficient way. Our work is motivated by the difficulty to constrain a mesh when adapting it to multi-view silhouette images. However, such an adaption(More)
Human pose estimation is a vivid topic in current literature due to its widespread applications such as motion-capture, telepresence or object manipulation in virtual environments. The process of human pose estimation is concerned with finding the pose parameters of a human body model that best fit to the observations in one or more input images. There(More)
Hydrophobic bile acids may cause hepatocellular necrosis and apoptosis during cholestatic liver diseases. The mechanism for this injury may involve mitochondrial dysfunction and the generation of oxidant stress. The purpose of this study was to determine the relationship of oxidant stress and the mitochondrial membrane permeability transition (MMPT) in(More)
We examined the role of cholesterol in altering the activity of the microsomal cytochrome P-450 enzyme, cholesterol-NADPH:oxygen oxidoreductase (cholesterol 7 alpha-hydroxylase). Liposomes were used to deliver cholesterol to hepatic microsomes. Formation of 7 alpha-hydroxycholesterol was quantitated by isotope dilution/gas chromatography-mass spectrometry.(More)
Many mixed reality systems require the real-time capture and re-rendering of the real world to integrate real objects more closely with the virtual graphics. This includes novel view-point synthesis for virtual mirror or telepresence applications. For real-time performance, the latency between capturing the real world and producing the virtual output needs(More)
We present a system that allows users to interactively control a 3D model of themselves at home using a commodity depth camera. It augments the model with virtual clothes that can be downloaded. As a result, users can enjoy a private, virtual try-on experience in their own homes. As a prerequisite, the user needs to enter or pass through a multi-camera(More)
Virtual try-on applications have become popular because they allow users to watch themselves wearing different clothes without the effort of changing them physically. This helps users to make quick buying decisions and, thus, improves the sales efficiency of retailers. Previous solutions usually involve motion capture, 3D reconstruction or modeling, which(More)
Recent data obtained using cultured rat hepatocytes showed that bile acids do not inhibit bile acid synthesis, whereas cholesterol concentrations vary in parallel with bile acid synthesis (Davis et al. (1983. J. Biol. Chem. 258: 4079-4082). This led us to re-evaluate in vivo experiments upon which the consensus that bile acid synthesis is primarily(More)
—We present a novel approach to adapt a watertight polygonal model of the human body to multiple synchronized camera views. While previous approaches yield excellent quality for this task, they require processing times of several seconds, especially for high resolution meshes. Our approach delivers high quality results at interactive rates when a roughly(More)
The oxysterol 25-hydroxycholesterol acts both as a regulatory sterol determining the expression of genes governed by sterol regulatory elements and as a substrate for 7-alpha-hydroxylase, the first and rate-limiting enzyme in the bile acid synthetic pathway. Most wild-type nonhepatic cells are killed by the cytotoxic action of 25-hydroxycholesterol. In(More)
