....the input images, or a cyclopian view in between some of the images. Other approaches, in particular multi view stereo methods, use multi valued [113] voxel based [101, 67, 34, 33, 24] or layer based [125, 5] representations. Still other approaches use full 3D models such as deformable models [120, 121], triangulated meshes [43] or level set methods [38] Since our goal is to compare a large number of methods within one common framework, we have chosen to focus on techniques that produce a univalued disparity map d(x, y) as their output. Central to such methods is the concept of a disparity ....
.... 34, 33, 24] Another way to represent a scene with more complexity is to use multiple layers, each of which can be represented by a plane plus residual parallax [5, 14, 117] Finally, deformable surfaces of various kinds have also been used to perform 3D shape reconstruction from multiple images [120, 121, 43, 38]. 3.6. Summary of methods Table 1 gives a summary of some representative stereo matching algorithms and their corresponding taxonomy, i.e. the matching cost, aggregation, and optimization techniques used by each. The methods are grouped to contrast different matching costs (top) aggregation ....

.... on control (or other) points during user modification of the shape of the surface [5, 25] Such approaches are often referred to as physics based modelling : changes in shape of a dynamically deformable surface are controlled by a set of virtual springs attached to it, constraining its shape [20]. A survey is provided by Gibson [8] Later work has included other constraints such as forces caused by collision between surfaces, and is commercially available in software provided by such companies as MathEngine. 4 Very similar technology is widely used in computer vision for finding and ....

....images to recover object shapes [1] They are classified as either parametric active contours (cf. 1 3] or geometric active contours (cf. 4 7] according to their representation and implementation. In particular, parametric active contours are represented explicitly as parameterized curves [1, 8] in a Lagrangian formulation. Geometric active contours are represented implicitly as level sets of twodimensional distance functions [9 11] which evolve according to an Eulerian formulation. They are based on the theory of curve evolution implemented via level set techniques [12] Parametric ....

....case, the modelling task is carried out in a natural and user friendly way, exactly like during clayworks. Many research works have been carried out on simulation of such deformations using physical laws: Finite Element method [Pen89] Wie97] Deb00] methods based on elasticity theory [Deb00] [Ter88] [Don01] particle systems [Ree83] Des96] etc. So far, none of these methods allows real time interaction with the user : they require much too long computation time for complex shapes and are not suitable for human interaction. Some researches are undergoing on volume sculpting in a 3D virtual ....

.... and its applications may be found in the text by Maia and Silva [13] Modal analysis was first introduced to the graphics community in 1989 by Pentland and Williams as a fast method for approximating deformation [19] They used a hybrid framework, previously described by Terzopoulos and Fleischer [24], that separated the motion of a deformable solid into a rigid component and a deformation component. The deformable component existed in a non inertial reference frame that moved with the rigid component. To avoid the cost of computing the modes for a particular object Pentland and Williams used ....

....the curve itself and external forces computed from image data. The internal and external forces are defined so that the snake will conform to an object boundary or other desired features within an image. Snakes are widely used in many applications, including edge detection[i] shape modeling [2], 3] segmentation[4] 5] and motion tracking[4] 6] There are in general two types of active contours presently: parametric[i] and geometric[7] 9] There have been several attemps to increase the capture range of parametric snakes through balloon model[12] through multiresolution scheme[14] ....
