A Statistically Efficient Method for Ellipse Detection
نویسندگان
چکیده
In this paper, we introduce a statistically efficient method f o r detecting ellipses in a n image. Given a set of digital arc segments, we introduce geometric criteria t o select possible pairs of arc segments belonging to the same ellipse. T h e selected arc pairs are subsequently validated or rejected based o n certain statistical criteria via hypothesis testing. The advantages of our technique include: 1) the proposed criteria are scaleinvariant; and 2) they can automatically adapt t o the noise characteristics of each image and do not need t o be adjusted empirically. Performance evaluation of our technique with real images demonstrates its good performance.

A New Efficient Ellipse Detection Method
In this paper, we introduce a new method for ellipse detection. This method takes the advantages of major axis of an ellipse to find ellipse parameter fast and efficiently. It only needs an one-dimensional accumulator array to accumulate the length information for minor axis of the ellipse. This method does not require the evaluation of the tangents or curvatures of the edge contours, which are...
متن کاملEllipse Detection through Decomposition of Circular Arcs and Line Segments
In this work we propose an efficient and original method for ellipse detection which relies on a recent contour representation based on arcs and line segments [1]. The first step of such a detection is to locate ellipse candidate with a grouping process exploiting geometric properties of adjacent arcs and lines. Then, for each ellipse candidate we extract a compact and significant representatio...
متن کاملEdge curvature and convexity based ellipse detection method
In this paper, we propose a novel ellipse detection method for real images. The proposed method uses the information of edge curvature and their convexity in relation to other edge contours as clues for identifying edge contours that can be grouped together. A search region is computed for every edge contour that contains other edge contours eligible for grouping with the current edge contour. ...

This paper describes a real time face detection and tracking system. The method consists in modelling the skin face by a pixel fusion process of three colour sources within the framework of the Demster-Shafer theory. The algorithm is composed of two phases. In a simple and fast initialising stage, the user selects successively on an image, a shadowy, an overexposed and a zone of mean intensity ...
متن کاملA Fast and Robust Ellipse-Detection Method Based on Sorted Merging
A fast and robust ellipse-detection method based on sorted merging is proposed in this paper. This method first represents the edge bitmap approximately with a set of line segments and then gradually merges the line segments into elliptical arcs and ellipses. To achieve high accuracy, a sorted merging strategy is proposed: the merging degrees of line segments/elliptical arcs are estimated, and ...
