Ellipse Fitting Using Orthogonal Hyperbolae and Stirling's Oval

نویسنده

  • Paul L. Rosin
چکیده

Two methods for approximating the normal distance to an ellipse using a) its orthogonal hyperbolae, and b) Stirling’s oval are described. Analysis with a set of quantitative set of measures shows that the former provides an accurate approximation with little irregularities or biases. Its suitability is evaluated by comparing several approximations as error of fit functions and applying them to ellipse fitting.

Guaranteed Ellipse Fitting with the Sampson Distance

When faced with an ellipse fitting problem, practitioners frequently resort to algebraic ellipse fitting methods due to their simplicity and efficiency. Currently, practitioners must choose between algebraic methods that guarantee an ellipse fit but exhibit high bias, and geometric methods that are less biased but may no longer guarantee an ellipse solution. We address this limitation by propos...

A note on the least squares fitting of ellipses

Rosin, P.L., A note on the least squares fitting of ellipses, Pattern Recognition Letters 14 (1993) 799-808. The characteristics of two normalisations for the general conic equation are investigated for use in least squares fitting: either setting F = 1 or A + C= 1. The normalisations vary in three main areas: curvature bias, singularities, transformational invariance. It is shown that setting ...

Action Recognition in Meeting Videos Using Head Trajectories and Fuzzy Color Histogram

People attending teleconference meetings usually follow specific trajectories corresponding to their intentions. In most situations the meeting video content can by sufficiently characterized by capturing the head trajectories. The tracking of the head is done using a particle filter built on cues such as color, gradient and shape. The head is represented by an ellipse with fuzzy color histogra...

Direct type-specific conic fitting and eigenvalue bias correction

A new method to fit specific types of conics to scattered data points is introduced. Direct, specific fitting of ellipses and hyperbolae is achieved by imposing a quadratic constraint on the conic coefficients, whereby an improved partitioning of the design matrix is devised so as to improve computational efficiency and numerical stability by eliminating redundant aspects of the fitting procedu...

Geometric Interpretation and Precision Analysis of Algebraic Ellipse Fitting Using Least Squares Method

This paper presents a new approach for precision estimation for algebraic ellipse fitting based on combined least squares method. Our approach is based on coordinate description of the ellipse geometry to determine the error distances of the fitting method. Since it is an effective fitting algorithm the well-known Direct Ellipse Fitting method was selected as an algebraic method for precision e...
