As a computational bridge between the high-level a priori knowledge of object shape and the low-level image data, active contours (or snakes) are useful models for the extraction of deformable objects. We propose an approach for manipulating multiple snakes iteratively, called interacting snakes, that minimizes the attraction energy functionals on both contours and enclosed regions of individua...

This papor dcsc.ribcs a new hair repre.sentation techiiiqiui for drawing 3D CG characters. In our approach liair models are representcid by skeleton-based implicit surfaces. Implicit inodoliiig allow.s ropresiuitlng union and division of wisp.s of hair by n.sing a blobby model. Our method gets hair skele tons as input data. The skeleton is interpolated using a spline function and then implicit ...

Age-dependent hearing loss involves pathological changes affecting the peripheral as well as the central auditory system. The Mongolian Gerbil is a rodent with an average life span of 3-4 years, which shows, in contrast to mice and rats, sensitive hearing in the frequency range that is important for human communication. Consequently, gerbils have been used to study structural and functional asp...

ows are symbolic in that they imply an artistic interpretation of the characters and scene. For example, lighting plays an important role in suggesting a scene’s mood, while a character’s shadow shows where the character is standing. Highlighting also describes various aspects of the characters and objects in the scene. The highlight examples shown in Figure 1 were made with traditional cel ani...

This paper studies algorithms for decomposing a real image into the sum of cartoon and texture based on total variation minimization and secondorder cone programming (SOCP). The cartoon is represented as a function of bounded variation while texture (and noise) is represented by elements in the space of oscillating functions, as proposed by Yves Meyer. Our approach gives more accurate results t...

Monitored 3-Dimensional (3D) video experience can be utilized as “feedback information” to fine tune the service parameters for providing a better service to the demanding 3D service customers. The 3D video experience which includes both video quality and depth perception is influenced by several contextual and content related factors (e.g., ambient illumination condition, content characteristi...

BACKGROUND Hepatitis B serology is complex and a lack of knowledge in interpretation contributes to the inadequate levels of screening and referral for highly effective hepatitis antiviral treatments. This knowledge gap needs to be addressed so that current and future healthcare professionals are more confident in the detection and assessment of hepatitis B to improve the uptake of treatment an...

In this paper, we present a generative model for textured motion phenomena, such as falling snow, wavy river and dancing grass, etc. Firstly, we represent an image as a linear superposition of image bases selected from a generic and over-complete dictionary. The dictionary contains Gabor bases for point/particle elements and Fourier bases for wave-elements. These bases compete to explain the in...
