View morphing

by Steven M. Seitz, Charles R. Dyer - In Computer Graphics (SIGGRAPH’96 , 1996
"... Image morphing techniques can generate compelling 2D transitions between images. However, differences in object pose or viewpoint often cause unnatural distortions in image morphs that are difficult to correct manually. Using basic principles of projective geometry, this paper introduces a simple ex ..."

extension to image morphing that correctly handles 3D projective camera and scene transformations. The technique, called view morphing, works by prewarping two images prior to computing a morph and then postwarping the interpolated images. Because no knowledge of 3D shape is required, the technique may

View Interpolation for Image Synthesis

by Shenchang Eric Chen, et al.
"... Image-space simplifications have been used to accelerate the calculation of computer graphic images since the dawn of visual simulation. Texture mapping has been used to provide a means by which images may themselves be used as display primitives. The work reported by this paper endeavors to carry t ..."

are a structured set of views of a 3D object or scene, intermediate frames derived by morphing can be used to approximate intermediate 3D transformations of the object or scene. Using the view interpolation approach to synthesize 3D scenes has two main advantages. First, the 3D representation

The Space of Human Body Shapes: Reconstruction And Parameterization from Range Scans

by Brett Allen, Brian Curless, Zoran Popović - ACM TRANS. GRAPH , 2003
"... We develop a novel method for fitting high-resolution template meshes to detailed human body range scans with sparse 3D markers. We formulate an optimization problem in which the degrees of freedom are an affine transformation at each template vertex. The objective function is a weighted combination ..."

OntoMorph: A Translation System for Symbolic Knowledge

by Hans Chalupsky - In Principles of Knowledge Representation and Reasoning , 2000
"... A common problem during the life cycle of knowledge-based systems is that symbolically represented knowledge needs to be translated into some different form. Translation needs occur along a variety of dimensions, such as KR language syntax and expressivity, modeling conventions, representation parad ..."

paradigms, etc. As a tool to support the translation problem, we present the OntoMorph system. OntoMorph provides a powerful rule language to represent complex syntactic transformations, and it is fully integrated with the PowerLoom KR system to allow transformations based on any mixture of syntactic

Recent Advances in Mesh Morphing

by Marc Alexa , 2002
"... Meshes have become a widespread and popular representation of models in computer graphics. Morphing techniques aim at transforming a given source shape into a target shape. Morphing techniques have various applications ranging from special effects in television and movies to medical imaging and sc ..."

Face Morphing

by Alex (yu Li , 2009
"... Face morphing, a specific case of geometry morphing, is a powerful tool for animation and graphics. It consists of the fluid transformation of one 3D face mesh to another. Its application spans a vast range of fields, anywhere from character animation for films and advertising to facial ..."

Volume Morphing Methods for Landmark Based 3D Image Deformation

by Shiaofen Fang, Raghu Raghavan, Joan T. Richtsmeier - in SPIE International Symposium on Medical Imaging , 1996
"... Volume morphing is a technique used for generating smooth 3D image transformations and deformations. In this paper, several algorithms are developed for morphing transformations that create new forms and simulate shape deformation and growth in biomedical applications. 3D biological point landmarks ..."

Pyramid Coordinates for Morphing and Deformation

by Alla Sheffer, Vladislav Kraevoy , 2004
"... Many model editing operations, such as morphing, blending, and shape deformation, require the ability to interactively transform the surface of a model in response to some control mechanism. For most computer graphics applications, it is important to preserve the local shape properties of input mode ..."

High Quality Voice Morphing

by Hui Ye, Steve Young , 2004
"... Voice morphing is a technique for modifying a source speaker’s speech to sound as if it was spoken by some designated target speaker. Most of the recent approaches to voice morphing apply a linear transformation to the spectral envelope and pitch scaling to modify the prosody. Whilst these methods a ..."

Morphing ensemble kalman filters

by Jonathan D. Beezley, Jan M - Tellus 60A (2007) 131
"... A new type of ensemble filter is proposed, which combines an ensemble Kalman filter (EnKF) with the ideas of morphing and registration from image processing. This results in filters suitable for nonlinear problems whose solutions exhibit moving coherent features, such as thin interfaces in wildfire ..."

by the user. The morphing EnKF operates on a transformed state consisting of the registration mapping and the residual. Essentially, the morphing EnKF uses intermediate states obtained by morphing instead of linear combinations of the states. 1
