We describe an interactive system to reconstruct 3D geometry and extract textures from a set of photographs taken with arbitrary camera parameters. The basic idea is to let the user draw 2D geometry on the images and set constraints using these drawings. Because the input comes directly from the user, he can more easily resolve most of the ambiguities and(More)
The gene encoding cellular retinol (ROL, vitA)-binding protein type I (CRBPI) has been inactivated. Mutant mice fed a vitA-enriched diet are healthy and fertile. They do not present any of the congenital abnormalities related to retinoic acid (RA) deficiency, indicating that CRBPI is not indispensable for RA synthesis. However, CRBPI deficiency results in(More)
Retinitis pigmentosa is an inherited degenerative disease of photoreceptors leading to blindness. A well-characterized model for this disease is provided by the retinal degeneration mouse, in which the gene for the rod cGMP phosphodiesterase is mutated, as in some affected human families. We report that D-cis-diltiazem, a calcium-channel blocker that also(More)
In our method, real scene geometry is first approximately reconstructed from photographs. Additional images are taken from a single viewpoint with a real light in different positions to estimate reflectance. A filtering process is used to compensate for inaccuracies, and per image reflectances are averaged to generate an approximate diffuse reflectance(More)
PURPOSE To evaluate the neuroprotective potential of glial cell line-derived neurotrophic factor (GDNF) in the retinal degeneration (rd/rd) mouse model of human retinitis pigmentosa. METHODS Subretinal injections of GDNF were made into rd/rd mice at 13 and 17 days of age and electroretinograms (ERGs) recorded at 22 days. Control mice received saline(More)
PURPOSE Duchenne muscular dystrophy is frequently associated with a reduced amplitude of b-wave under scotopic conditions in the electroretinogram. This suggests that the dystrophin gene-encoded proteins play a role in retinal neurotransmission. The abnormal neurotransmission has been attributed to altered expressions of C-terminal products of the(More)
Modeling complex realistic objects is a difficult and time consuming process. Nevertheless, with improvements in rendering speed and quality, more and more applications require such realistic complex 3D objects. We present an interactive modeling system that extracts 3D objects from photographs. Our key contribution lies in the tight integration of a(More)

Methane (CH4) emissions were measured at the Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) over three summers and two winters using an eddy covariance system. We used an empirical model to determine the main environmental drivers of methane emissions. Methane emissions covary strongly with water vapor fluxes, CO2 fluxes, and soil(More)
