We present a novel progressive painting-based mesh cut out tool, called Paint Mesh Cutting, for interactive mesh segmentation. Different from the previous user interfaces, the user only needs to draw a single stroke on the foreground region and then obtains the desired cutting part at an interactive rate. Moreover, the user progressively paints the region of interest using a brush and has the i...

We consider the cooperative decay of incoherently pumped atoms in a disordered medium, where light undergoes multiple scattering. It is shown that the cooperation number, which determines the duration and amplitude of superfluorescent impulses, is given by the number of atoms along a diffusive trajectory of the light propagating through the medium. We also consider the problem of reflection of ...

Shapes, Paint, and Light by Jonathan Tilton Barron Doctor of Philosophy in Computer Science University of California, Berkeley Professor Jitendra Malik, Chair A fundamental problem in computer vision is that of inferring the intrinsic, 3D structure of the world from flat, 2D images of that world. Traditional methods for recovering scene properties such as shape, reflectance, or illumination rel...

It has been suggested that the epoxy paint used to coat metal substrates in industrial electrostatic painting applications could also be used to mask metal clasps in removable dental prostheses (RDP). The purpose of this study was to evaluate both the influence of thermal cycling and the in vitro roughness of a surface after application of epoxy paint, as well as to assess the micromorphology o...

Dried varnish is rich in many ester moieties, which may be broken down into small, soluble compounds by esterase activity or alkaline hydrolysis. Two methods for varnish removal have been developed, including the treatment of either lipase or RbOH / PEG-400 crown ether which allow aged oil varnishes or paint coverings to be removed or thinned. These techniques are designed to proceed in a contr...

Management methods for invasive species vary in their restoration success in the presence or absence of herbivores. We investigated the performance of understory plants after management of the invasive shrub Amur honeysuckle using two herbicide-based methods (cut/paint and basal application) in fenced and unfenced plots. The cut/paint method resulted in the removal of above-ground stems, while ...

A metallic paint scheme for an architectural wall is created using computer aided color appearance design techniques. New computer graphic hardware that allows real-time rendering of complex reflectance functions is employed to produce photo-realistic images of the metallic paint applied to the surface of the wall. An interpolation scheme is developed that permits one and two dimensional metall...

The computer graphic simulation of a common spray painting artifact, called orange peel, is discussed. Orange peel distorts surface reflections and is commonplace in product design applications. The orange peel measurements from a standard industrial instrument are used to construct a height field, and this surface is rendered using traditional normal mapping techniques. Comparisons are made be...

OBJECTIVE To determine the use of lead-based paint in public playgrounds in the municipalities of Johannesburg, Tshwane and Ekurhuleni. METHODS Forty-nine public parks were selected from the municipalities of Johannesburg, Tshwane and Ekurhuleni. Lead levels in paint on playground equipment were measured in situ using a hand-held Thermo Scientific NITON XLP 700 Series X-ray fluorescence (XRF)...
