An incremental Contour Method (iCM) of residual stress measurement is proposed where stresses in the body interest are sequentially reduced by successive contour cuts and risk re-distribution plasticity mitigated or eliminated. The cutting-induced known to cause significant inaccuracies when trying measure near-yield using a conventional single cut method. iCM procedure implements new displacem...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

A divide and conquer deformable contour method is presented with an initial inside closed contour being divided into arbitrary segments, and these segments are allowed to deform separately preserving the segments' connectivity. A maximum area threshold, A/sub max/, is used to stop these outward contour segments' marching. Clear and blur contour points are then identified to partition the whole ...

An object can be effectively characterized by its contour. Caselles et al. [1] introduced the concept of geodesic active contours, which applies the energy reducing form to acquire contours. Shape priors are great helpful to obtaining more accurate contours. Leventon [6] utilized the curvature prior as the shape prior for different classes of objects to guide contour evolution. Etyngier et al. ...

Contour line is the main linear feature on topographic maps. Extraction of contour lines is tedious and time-consuming process, and is still an interesting problem. A novel method for extraction of contour lines from paper-based topographic maps is presented in this paper. In our approach, we firstly segment color topographic maps for achieving the binary image of brown color contour lines. The...

Since interference noise and limited imaging algorithm etc caused low-quality images, continuous contour information on targets was difficult to extract, and ISAR imaging on aerial targets wasn’t ideal. On this basis, a new method of image processing is proposed to achieve clearer continuous contour features on targets. The method combines denoising technique based on Contourlet transform with ...

Pitch contours are important for synthesizing highly natural speech signal. In this paper, we study a new pitch-contour generation method. The method proposed is to combine ANN prediction module with global-variance matching (GVM) and real contour selection (RCS) modules. Here, a syllable pitch contour is first analyzed and then transformed via discrete cosine transform (DCT) to a DCT-coefficie...

In this paper we present a novel method for the segmentation of scintigraphic images in order to detect the two ventricles of the heart. The method is based on the active contour model using a region based approach and parametric representation of the contour. The novel aspect of the method is that we have integrated separating forces between the two ventricles in the active contour model. The ...

A higher order spline interpolated contour obtained with up-sampling of homogenously distributed coordinates for segmentation of kidney region in different classes of ultrasound kidney images has been developed and presented in this paper. The performance of the proposed method is measured and compared with modified snake model contour, Markov random field contour and expert outlined contour. T...
