This paper presents an unique method for rendering complex shapes as fuzzy or diffuse objects inside virtual environments. It uses surface geometry that is converted into a voxel-like grid to specify the appearance of the shape. A particle system displays the outline of the object at runtime. Particles are allowed to move freely inside the voxel-grid but obtain certain attributes from the voxel...

Detection of both scene text and graphic text in video images is gaining popularity in the area of information retrieval for efficient indexing and understanding the video. In this paper, we explore a new idea of classifying low contrast and high contrast video images in order to detect accurate boundary of the text lines in video images. In this work, high contrast refers to sharpness while lo...

the set of all non-increasing non-negative integer sequences $pi=(d_1‎, ‎d_2,ldots,d_n)$ is denoted by $ns_n$‎. ‎a sequence $piin ns_{n}$ is said to be graphic if it is the degree sequence of a simple graph $g$ on $n$ vertices‎, ‎and such a graph $g$ is called a realization of $pi$‎. ‎the set of all graphic sequences in $ns_{n}$ is denoted by $gs_{n}$‎. ‎the complete product split graph on $l‎ ...

To separate out objects in a live action video sequence, an artist must step through the footage, frame by frame, and rotoscope out the occluding object from the background where a 3D computer generated graphic is to be inserted. This slow and expensive process can be remedied with the use of light field photography to capture depth information with every frame of film. These depth maps can be ...

Tactation is the sensation perceived by the sense of touch. Kinesthetic information describes the relative positions and movements of body parts as well as muscular effort when touching and manipulating objects. Haptic perception involves both tactile perception through the skin and kinesthetic perception of the position and movement of the joints and muscles,through the skin of our fingers and...

Frame matroids and lifted-graphic matroids are two interesting generalizations of graphic matroids. Here we introduce a new generalization, quasi-graphic matroids, that unifies these two existing classes. Unlike frame matroids and lifted-graphic matroids, it is easy to certify that a matroid is quasi-graphic. The main result of the paper is that every 3-connected representable quasi-graphic mat...

Abstract Measurements of the surface velocity and texture a freely propagating shear jamming front in dense suspension are compared. The fields captured with particle image velocimetry (PIV), while is separated experiment by observing direct reflection on high-speed cameras. A method for quantifying features their orientation presented based fast Fourier transform localized windows. region that...

Exploring and editing colors in images is a common task in graphic design and photography. However, allowing for interactive recoloring while preserving smooth color blends in the image remains a challenging problem. We present LayerBuilder, an algorithm that decomposes an image or video into a linear combination of colored layers to facilitate color-editing applications. These layers provide a...
