Avoidance is a necessary capability for a mobile robot to perform tasks, such as delivering
objects in household or industrial scenarios. The existing avoidance strategy based on …

Existing edge detection methods are based on fixed logics, which are not intelligent enough
to distinguish useful edges and useless/noise edges. Recent ellipse detection methods …

Robotic manipulation employs the object detection in images to create a scene awareness
and locate an object's pose. In dynamic scenarios, fast multiobject detection and tracking are …

A lot of objects commonly found in industrial and household environments are represented
by cylindrical shapes (flange plates) and ellipsoids (oranges). The visual tops of cylindrical …

Accurate ellipse detection in image streams at real-time execution is an open challenge. We
present a novel fast and robust ellipse detection method. The method adopts arcs selection …

Countersinks have been widely used for flush rivets of aircraft panels. The quality of
countersinking significantly impacts the performance of riveted joints. Thus, a reliable …

This paper proposes a basic taxonomy of image contours. Our goal is to classify smooth
curves into five categories, namely, circles, ellipses, line segments, arcs of circles and arcs …

Robotic manipulation of objects requires a fast recognition from image stream. For many
cylindrical object (eg, cans, cups, pipes, bottles, etc.) this is possible through detection of …

针对软胶囊实时缺陷检测与丸形分级问题, 提出一种基于远心视觉的椭圆度测量方法及其系统.
以最小二乘椭圆作为评定基准, 用被测轮廓的最小外接椭圆和最大内接椭圆的通径定义椭圆度 …

In our daily life, there are many objects represented by cylindrical shapes and ellipsoids.
The tops of these objects are formed by elliptic shape primitives. Thus, it is available for a …
