Dynamic Contour Modeling of Wet Material Objects by Periodic Smoothing Splines
نویسندگان
چکیده
We present a new scheme for modeling the contour of wet material objects by employing optimal design of periodic smoothing spline surfaces. The surfaces are constructed using normalized uniform B-splines as the basis functions, namely as weighted sum of shifted bi-variable B-splines. Then a central issue is to determine an optimal matrix of the so-called control points. A concise representation for the optimal surfaces with periodic constraint is derived, which enable us to develop numerical computational procedures in a straightforward manner. The results are applied to the problem of modeling contour of wet material objects with deforming motion, and the effectiveness is examined by experimental studies.

Optimal Smoothing Spline Curves and Contour Synthesis
We consider a problem of designing optimal smoothing spline curves using normalized uniform B-splines as basis functions. Assuming that the data for smoothing is obtained by sampling some curve with noises, an expression for optimal curves is derived when the number of data becomes infinity. It is then shown that, under certain condition, optimal smoothing splines converge to this curve as the ...
متن کاملPeriodic and Recursive Control Theoretic Smoothing Splines
In this paper a recursive control theoretic smoothing spline approach is proposed for reconstructing a closed contour. Periodic splines are generated through minimizing a cost function subject to constraints imposed by a linear control system. The optimal control problem is shown to be proper and sufficient optimality conditions are derived for a special case of the problem using Hamilton-Jacob...

In this paper, a recursive smoothing spline approach for contour reconstruction is studied and evaluated. Periodic smoothing splines are used by a robot to approximate the contour of encountered obstacles in the environment. The splines are generated through minimizing a cost function subject to constraints imposed by a linear control system and accuracy is improved iteratively using a recursiv...
متن کاملA FILTERED B-SPLINE MODEL OF SCANNED DIGITAL IMAGES
We present an approach for modeling and filtering digitally scanned images. The digital contour of an image is segmented to identify the linear segments, the nonlinear segments and critical corners. The nonlinear segments are modeled by B-splines. To remove the contour noise, we propose a weighted least q m s model to account for both the fitness of the splines as well as their approximate cur...
متن کاملTrivariate Optimal Smoothing Splines with Dynamic Shape Modeling of Deforming Object
We develop a method of constructing trivariate optimal smoothing splines using normalized uniform B-spline as the basis functions. Such splines are useful particularly for modeling dynamic shape of 3-dimensional deformable object by using two variables for 3D shape and one for time evolution. The trivariate splines are constructed as a tensor product of three B-splines, and an optimal smoothing...
