Arbitrary-Shaped Text Detection with B-Spline Curve Network [PDF]
Sensors, 2023 Text regions in natural scenes have complex and variable shapes. Directly using contour coordinates to describe text regions will make the modeling inadequate and lead to low accuracy of text detection. To address the problem of irregular text regions in

B-spline curve fitting based on dynamic adjustment of knot vector using feature points. [PDF]
PLoS ONEAn essential challenge in B-spline curve fitting is how to produce a B-spline curve that satisfies the accuracy requirement with a minimal number of knots and control points. This paper suggests a better algorithm based on feature points method.

Approximating uniform rational B-spline curves by polynomial B-spline curves
Journal of Computational and Applied Mathematics, 2013 Approximation of rational B-spline curves by B-spline curves is an important issue in computer aided geometric design. This paper presents a method to approximate a uniform rational B-spline with B-spline curve sequence as follows. We first elevate the degree of the original rational B-spline curve and take the control points of the degree-elevated ...

Parameterization Method on B‐Spline Curve [PDF]
Mathematical Problems in Engineering, 2012 The use of computer graphics in many areas allows a real object to be transformed into a three‐dimensional computer model (3D) by developing tools to improve the visualization of two‐dimensional (2D) and 3D data from series of data point. The tools involved the representation of 2D and 3D primitive entities and parameterization method using B‐spline ...

Quadratic B-Spline Surfaces with Free Parameters for the Interpolation of Curve Networks
Mathematics, 2022 In this paper, we propose a method for constructing spline surfaces interpolating a B-spline curve network, allowing the presence of free parameters, in order to model the interpolating surface.

Dynamic Centripetal Parameterization Method for B-Spline Curve Interpolation
IEEE Access, 2020 B-spline data interpolation and approximation require parameterization at the first step. For this purpose, many algorithms have been developed, such as the uniform, centripetal, chord length, Foley and universal methods. The uniform method works well if
