In recent years, machine vision has played an important role in product surface quality
detection. The promotion and use of this technology have largely avoided the subjectivity …

Curve reconstruction from unstructured points in a plane is a fundamental problem with
many applications that has generated research interest for decades. Involved aspects like …

In this article, we propose a Multi-feature Fusion VoteNet (MFFVoteNet) framework for
improving the 3D object detection performance in cluttered and heavily occluded scenes …

Airfoil blades are typically inspected in sections to verify their conformance to the geometric
tolerances specified on their nominal design. To maintain the accuracy of geometric error …

Many studies have used Global Navigation Satellite System (GNSS) traces to successfully
extract segments of road networks because such data can be rapidly updated at a low cost …

When creating freeform drawings, artists routinely employ clusters of overdrawn strokes to
convey intended, aggregate curves. The ability to algorithmically fit these intended curves to …

The problem of fitting B-spline curves to planar point clouds is studied in this paper. A novel
method is proposed to deal with the most challenging case where multiple intersecting …

Recent 3-D scanning techniques can produce various kinds of digitized 3-D data. Most of
these scanned data are in a format of unstructured point clouds. Such low-level …

We propose a point segmentation and grouping method to generate road maps from GPS
traces. First, we present a progressive point cloud segmentation algorithm based on Total …

Given a planar point set sampled from a curve, the curve reconstruction problem computes a
polygonal approximation of the curve. In this paper, we propose a Delaunay triangulation …
