Deformable models using displacement constraints
… [19], used for creating and animating deformable objects. It is a constraint-based technique that uncouples the constraint forces from the external forces acting on an object, and solves a system of geometric constraints at each time step using an iterative technique. Displacement …

Learning deformable models for tracking human motion
… non-rigid objects require complex hand-crafted models which are not easily adapted to different problems. A more recent approach uses training information to build models for image analysis. This thesis extends this approach by building flexible 2D models, automatically, from sequences of …

Automatic 3D facial modelling with deformable models.
… with range scans in different scales, and a deformable model, which can be used to recover the shapes of range scans and to establish correspondences between facial models. With the registration method and the deformable model, the author proposed a fully automatic approach to reconstructing …

Registration of images containing rigid structures using deformable models and its medical application
… of images containing rigid structures using deformable models. In the existing methods of deformable image registration, the feature based methods using purely interpolation are often used under the assumption that all parts of the image can be deformed non-linearly. However, it is not …

Segmentation of candidate bacillus objects in images of Ziehl-Neelsen-stained sputum smears using deformable models
… here, the use of parametric and geometric deformable models was explored for segmentation of TB bacilli in images of Ziehl-Neelsen-stained sputum smears for automated TB diagnosis. The goal of segmentation is to produce candidate bacillus objects for input into a classifier.

System for Collision Detection Between Deformable Models Built on Axis Aligned Bounding Boxes and GPU Based Culling
Collision detection between deforming models is a difficult problem for collision detection systems to handle. This problem is even more difficult when deformations are unconstrained, objects are in close proximity to one another, and when the entity count is high. We propose a method to perform …

Representation and detection of shapes in images
… detection of non-rigid objects in images using deformable models. We present an efficient algorithm to solve this problem in a wide range of situations, and show examples in both natural and medical images. We also consider the problem of learning an accurate non-rigid shape model for a class of …

The development of finite element model for Malaysian Female Anthropometric Dummy
… for user safety. The development of dummy models starts from rigid body models to deformable models which is then adopted into finite element models for more accurate and detailed results in doing analysis. Using the numerical method (FEM) to evaluate crash test has increase the cost saving …

Probabilistic Multi-Compartment Deformable Model, Application to Cell Segmentation
… not perform well. The proposed method combines deformable models with a probabilistic framework in a simple graphical model such that it would capture the shape, structure and appearance of a cell. The process aims at the simultaneous cell partitioning into nucleus and cytoplasm. We considered …

A Numerical Elastic Model for Deforming Bat Pinnae
In bats, the directivity patterns for reception are shaped by the surface geometry of the pinnae. Since many bat species are capable of large ear deformations, these beampatterns can be time-variant. To investigate this time-variance using numerical methods, a digital model that is capable of …

Hand detection on images based on deformable part models and additional features
… objects, and has been released with a successful deformable parts model in VOC2007. A hand detection on an image is made when the system gets a bounding box which overlaps with at least 50% of any ground truth bounding box for a hand on the image. The initial average precision of this detector is …
