Image Manifold Interpolation using Free-Form Deformations
2006 International Conference on Image Processing, 2006An important class of image data sets depict an object undergoing deformation. When there are only a few underlying causes of the deformation, these images have a natural low-dimensional structure which can be parameterized using manifold learning. This paper presents a method to solve for the deformation field as a function of the manifold coordinates

Dynamic free-form deformations for animation synthesis
IEEE Transactions on Visualization and Computer Graphics, 1997Free form deformations (FFDs) are a popular tool for modeling and keyframe animation. The paper extends the use of FFDs to a dynamic setting. Our goal is to enable normally inanimate graphics objects, such as teapots and tables, to become animated, and learn to move about in a charming, cartoon like manner.

Fully free-form deformation features for aesthetic shape design
Journal of Engineering Design, 2005Geometric models, such as B-Rep or CSG, are often used as a shared reference representation of the product along the whole design process. However, they do not provide capabilities for conveying complex information related to the involved product development tasks.

Fully Free-Form Deformation Features (δ-F4) Incorporating Discontinuities
Volume 1: 30th Design Automation Conference, 2004To limit low-level manipulations of free-form surfaces, the concept of Fully Free Form Deformation Features (δ-F4) have been introduced. They correspond to shapes obtained by deformation of a surface area according to specified geometric constraints. In our work, we mainly focused on those features aimed at enforcing the visual effect of the so-called ...

Fast free-form deformable registration via calculus of variations
Physics in Medicine and Biology, 2004In this paper, we present a fully automatic, fast and accurate deformable registration technique. This technique deals with free-form deformation. It minimizes an energy functional that combines both similarity and smoothness measures. By using calculus of variations, the minimization problem was represented as a set of nonlinear elliptic partial ...

Free-Form Deformation Axis Aligned Bounding Box
2009We present a new efficient collision-handling technique of free-form deformation (FFD) of an embedded surface. By adapting FFD, modeling deformation has been substantially simplified to make possible interactive rate animation of a deformable object even for a complex embedded mesh.

Multiple-Points Constraints Based Deformation for Free-Form Surfaces
Volume 1: 25th Design Automation Conference, 1999Abstract There is an increasing demand in the conceptual design for more intuitive methods for creating and modifying free-form curves and surfaces in CAD modeling systems. The methods should be based not only on the change of the mathematical parameters but also on the user’s specified constraints and shapes.

Non-rigid registration using free-form deformations
2015Free-form deformations are a powerful geometric modeling technique which can be used to represent complex 3D deformations. In recent years, free-form deformations have gained significant popularity in algorithms for the non-rigid registration of medical images.
