A Data-Driven Approach to Realistic Shape Morphing
Morphing between 3D objects is a fundamental technique in computer graphics. Traditional methods of shape morphing focus on establishing meaningful correspondences and finding smooth interpolation between shapes. Such methods however only take geometric information as input and thus cannot in general avoid producing unnatural interpolation, in particular for large-scale deformations. This paper...
متن کامل3D shape and 2D surface textures of human faces: the role of "averages" in attractiveness and age
Recent work in the psychological literature has indicated that attractive faces are in some ways “average” [J.H. Langlois, L.A. Roggman, Attractive faces are only average, Psychological Science, 1(2) (1990) 115–121] and that the apparent age of a face can be related to its proximity to the average of a computationally derived “face space” [A.J. O’Toole, T. Vetter, H. Volz, E.M. Salter, Three-di...
متن کاملShape Morphing of Complex Geometries Using Partial Differential Equations
An alternative technique for shape morphing using a surface generating method using partial differential equations is outlined throughout this work. The boundaryvalue nature that is inherent to this surface generation technique together with its mathematical properties are hereby exploited for creating intermediate shapes between an initial shape and a final one. Four alternative shape morphing...
متن کاملObject Shape Morphing with Intermediate Reflectance Properties
Image morphing techniques can create a smooth transition between two images. However, one of the main weakness of the image morphing technique is that intermediate images in the transition often have physically incorrect shading such as highlights and shadows. Moreover, we cannot alter viewing and lighting conditions when creating the intermediate images. That is because those images are obtain...
متن کاملRecent Advances in Mesh Morphing
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 scientific visualization. Not surprisingly, morphing techniques for meshes have received a lot of int...
