An object is called deformable when its shape can be altered according to external stimuli. Contrary to rigid objects, which have a fixed shape, most human organs as well as tissues are deformable. Although rigid objects require for their simulation only translation and rotation properties to be defined, deformable objects demand also deformation parameters to be evaluated, which is usually a c...

A simple but robust control law for the grasping manipulation of deformable objects is presented. In the handling of deformable objects, grasping and manipulation must be performed simultaneously despite uncertainties during the handling process. We will propose a control law to perform grasping and manipulation of deformable objects using a realtime vision system.

This thesis deals with surface extraction from noisy volumetric images, which is a common problem in medical image analysis. Due to noise, the use of a-priori information about surface topology and shape is necessary for automatic surface extraction methods. Deformable surface models can incorporate such geometric knowledge into extraction process which is restated as an energy minimization pro...

From the ardent bucklers used during the Syracuse battle to set fire to Romans’ ships to more contemporary piezoelectric deformable mirrors widely used in astronomy, from very large voice coil deformable mirrors considered in future Extremely Large Telescopes to very small and compact ones embedded in Multi Object Adaptive Optics systems, this paper aims at giving an overview of Deformable Mirr...

Customising PRESAGE® for diverse applications T Juang, J Newton, M Niebanck, R Benning, J Adamovics and M Oldham 2013 J. Phys.: Conf. Ser. 444 012029 PRESAGE® is a solid radiochromic dosimeter consisting of a polyurethane matrix, a triarylmethane leuco dye, and a trihalomethane initiator. Varying the composition and/orrelative amounts of these constituents can affect the dose sensitivity, post-...

Manipulation of deformable objects will be discussed. Manipulation of deformable objects is de ned as controlling deformation of objects as well as their positions and orientations. The manipulation is a fundamental and important task in many industrial elds. In fact, there exist many operations of deformable objects such as textile fabrics, rubber parts, paper sheets, strings, and foods. In or...

The interactions of deformable drops in cavity flows is studied numerically in the limit of low Reynolds numbers for a two-dimensional model. Flow in a square cavity is driven by the steady motion of one of the walls. Deformable drops will migrate across streamlines until they reach an equilibrium trajectory or equilibrium position; the rate and direction of migration depend on both the viscosi...

This paper reviews model based methods for non rigid shape analysis and recognition These methods model match and classify non rigid shapes which are generally problematic for conventional algorithms using rigid models Issues including deformable model represen tation optimization criteria formulation model matching and classi cation are examined in detail The emphasis of this paper is on D def...

Using a force feedback device within the framework of deformable object simulation remains difficult because of the incompatibility between the computation time needed by realistic deformable models and high refresh frequencies necessary for real-time haptic rendering. Giving the user a good haptic sensation requires refreshing the applied forces at least ten times more often than for giving a ...
