In random sample consensus (RANSAC), the problem of ellipsoid fitting can be formulated
as a problem of minimization of point-to-model distance, which is realized by maximizing …

The performance of ellipse fitting may significantly degrade in the presence of outliers, which
can be caused by occlusion of the object, mirror reflection or other objects in the process of …

Ellipse fitting is widely applied in the fields of computer vision and automatic manufacture.
However, the introduced edge point errors (especially outliers) from image edge detection …

Ellipse shapes taken by a projection lens encode rich semantic information, and ellipse
detection is an important and convenient means to obtain spatial semantics from images …

Diameter detection plays an important role in the production of circular workpieces. It is very
difficult to obtain the accurate measurement of diameter when the circular workpiece is red …

Fast and efficient fitting of accurate ellipses from data points has many applications in
pattern recognition, machine vision, and robotics. However, the fitting accuracy may …

Quick and accurate ellipse detection is essential for computer vision, automatic
manufacturing, and other fields. In order to obtain more accurate ellipse parameters, the …

Single point strain analysis (SPSA) is a software developed to measure surface strains in
sheet metal forming operations. For this, the images of deformed circular and square grids …

Auto diameter measurement plays an important role in Czochralski method for silicon single
crystals. In this paper, a novel approach based on concentric ellipses is proposed to …

Growth striations, as macrodefects of crystalline materials, are mainly caused by convection
and temperature fluctuations in growth interface. For decades, striations have been widely …
