In early geological data analysis, most geological maps were drawn as raster images by
hand or with software, and there were disadvantages such as the inability to edit at any time …

Radiation therapy plays an essential role in the treatment of cancer. In radiation therapy, the
ideal radiation doses are delivered to the observed tumor while not affecting neighboring …

Geometric iterative methods (GIM), including the progressive–iterative approximation (PIA)
and the geometric interpolation/approximation method, are a class of iterative methods for …

Nitrate pollution in groundwater has become a widespread problem worldwide, but
understanding of the factors influencing groundwater nitrate pollution remains limited …

摘要提出基于渐进迭代逼近(Progressive Iteration Approximation, PIA) 的非均匀三次B
样条曲线Hermite 插值算法. 首先, 以给定数据点作为初始控制顶点, 采用累加弦长法得到节点 …

In order to improve detection system robustness and reliability, multi-sensors fusion is used
in modern air combat. In this paper, a data fusion method based on reinforcement learning is …

Polyline and building simplification remain challenging in cartography. Most proposed
algorithms are geometric-based and rely on specific rules. In this study, we propose a deep …

This paper presents a unified framework for computing a B-spline curve to approximate the
micro-line toolpath within the desired fitting accuracy. First, a bi-chord error test extended …

NURBS are widely used in the design of free curves and surfaces and have been the
industrial standard for product design in CAD/CAM. Ship hull surfaces are complex doubly …

Implicit curve and surface reconstruction attracts the attention of many researchers and
gains a wide range of applications, due to its ability to describe objects with complicated …
