A static analysis of deformable object grasping based on bounded force closure is presented. There are many manipulative operations that deal with deformable objects in manufacturing processes. Manipulative operations for these objects are often performed by utilizing their deformation actively while the operations may result in failure because of unexpected deformation of the objects during th...

This paper proposes a non-self-intersecting multiscale deformable surface model with an adaptive remeshing capability. The model is specifically designed to extract the three-dimensional boundaries of topologically simple but geometrically complex anatomical structures, especially those with deep concavities such as the brain, from volumetric medical images. The model successfully addresses thr...

One of the most critical steps in the process of digital image analysis is segmentation: separation of an image into regions that have strong correlation with objects of the real world. Segmentation of fiber like objects is a key problem in several image processing application. This paper overviews deformable models, as well as segmentation techniques employed for fiber like objects and propose...

Methods of deformable appearance models are useful for realistically modelling shapes and textures of visual objects for reconstruction. A first application can be the fine analysis of face gestures and expressions from videos, as deformable appearance models make it possible to automatically and robustly locate several points of interest in face images. That opens development prospects of tech...

Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medi...

This paper describes a new approach to the tracking of complex shapes through image sequences, that combines deformable region models and deformable contours. A new deformable region model is presented: its optimisation is based on texture correlation and is constrained by the use of a motion model, such as rigid, aane or homographic. The use of texture information (versus edge information) not...

Volumetric models provide a realistic representation of three dimensional objects above and beyond what traditional surface models offer. The finite element method along with a volumetric model of an object can be used to create an effective representation of a deformable object that responds properly to external forces and stimuli. In particular, cutting is an important feature in many applica...

We present the work that has been done on segmentation of abdominal aortic aneurysm (AAA) by Image Processing Group on Faculty of Electrical Engineering and Computing in Zagreb. We investigated performance of two types of deformable models: parametric and geometric deformable models both operating on three-dimensional data sets obtained by computer tomography angiography (CTA). Both inner and o...

In this paper we present two modifications to the original level set algorithm for implementation of deformable models. The modifications are motivated by difficulties that we have encountered in application of deformable models to segmentation of abdominal aortic aneurysm from computed tomography images. The level set algorithm has some advantages over the classical snake deformable models but...

In this paper we present a newmethod for approximating non-linear dynamics in deformable simulations based on a full cubic polynomial formulation of the inter-particle force. The proposed approach is a non-physical extension of the well known St Venant Kirchhoff force, focusing on practical considerations about the behavior of the deformable model. Therefore it is very useful for simulating and...
