Fat conic section and fat conic spline are defined. With well established properties of fat conic splines, the problem of approximating a ruled surface by a tangent smooth cone spline can then be changed as the problem of fitting a plane fat curve by a fat conic spline. Moreover, the fitting error between the ruled surface and the cone spline can be estimated explicitly via fat conic spline fit...
مکان یابی هدف از گذشته مورد توجه بسیاری از کارهای پژوهشی انجام گرفته در عرصه¬های مخابراتی می باشد. امروزه با توجه به ظهور شبکه¬های حسگر بی سیم، مکان یابی با استفاده از این شبکه¬ها دارای اهمیت به سزایی است. یکی از مهمترین روش¬های موجود، مکان یابی هدف با اندازه گیری اختلاف زمان ورود سیگنال¬ها و با بهره گیری از روش بیش ترین شباهت می باشد. از مزایای استفاده از این روش دقت بالاتر آن و بهینه بودن مجا...
B-Splines have been popular for several purposes. In this work, B-Splines are used for modeling noisy multivariate data. A new algorithm is proposed to approximate image data with B-Spline surfaces, where image data is assumed to be corrupted by Gaussian noise mixed with outliers. The resulting surface gives a restored continuous representation of discrete data while preserving edges. A gradien...
Contour detection has a rich history in multiple fields such as geography, engineering, and earth science. The predominant approach is based on piecewise planar tessellation now being challenged concerning the extraction of contour objects for non-linear elevation functions, particularly with respect to bicubic spline functions. A storage-efficient method was developed previous research, but co...
In this paper we construct an information-theoretic model of architectural drawings. This model is then used to quantify and measure the complexities and similarities of drawings. The approach is applied within a linear qualitative shape representation but can be generalized to other types of representation. The descriptive and analytic power of the proposed methods are demonstrated by studying...
