We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across different sublayers, while it can be neglected within each of the sublayers. Based on this assumption, an efficient recursive procedure of assembling the layers is developed, which...

In surgery one of the major problems is a safe approach of the operation site. For surgeons it is paramount to know the location of surgically relevant nerves and vessels. Especially in surgery of the lateral (outside) foot, the anatomy is not always completely clear since the location of nerves and vessels is highly variable. Therefore CASAM is developed by students in Delft and Rotterdam (Net...

• Deals with problem of corresponding open curves where endpoints are not defined (ie best correspondence would involve missing of end parts of some curves) • Uses thin-plate spline bending energy to measure quality of correspondence • Treats problem in pairwise manner • Initial landmarks can slide along boundary to minimise obj.fn. • Seems to fix one shape as template, clip a proportion off an...

The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

By coupling the flexibility of Thin-Plate Splines interpolation with Green’s integral formula, we obtain a meshless cubature method from scattered samples of small/moderate size, on convex as well as nonconvex and even multiply connected polygonal domains. 2000 AMS subject classification: 65D05, 65D32.

In this paper, we present an automatic face authentication system. Accurate segmentation of prominent facial features is accomplished by means of an extension of the Active Shape Model (ASM) approach, the so-called Active Shape Model with Invariant Optimal Features (IOF-ASM). Once the face has been segmented, a pose correction step is applied, so that frontal face images are synthesized. For th...

A novel elastic image registration approach is proposed, which can register both 2D medical images and gel electrophoresis automatically and accurately. Firstly, the global affine registration method based on image intensity is used to initialise a starting estimation of the robust registration algorithm. Then, by using iterative landmark based algorithm, the affine registration results are reg...

Previous work on nonrigid registration of medical images based on thin plate splines has concentrated on using interpolation schemes Such schemes force the corresponding land marks to exactly match each other and thus assume that the landmark positions are known exactly However in real applications the localization of landmarks is always prone to error Therefore to cope with these errors we hav...

In this work, a novel and generic method for example-based color transfer is presented. The color transfer is formulated in two steps: first, an example-based Chromatic Adaptation Transform (CAT) has been designed to obtain an illuminant matching between input and example images. Second, the dominant colors of the input and example images are optimally mapped. The main strength of the method co...

Background: In nuclear medicine application often it is required to use computational methods for evaluation of organ absorbed dose. Monte Carlo simulation and phantoms have been used in many works before. The shape, size and volume in organs are varied, and this variation will produce error in dose calculation if no correction is applied. Materials and Methods: A computational framewo...
