Randomized circle detection with isophotes curvature analysis

作者:

Highlights:

• An iterative randomized circle detection algorithm is proposed.

• Curvature of isophotes is used to reduce the number of necessary iterations.

• Edges on circumference(s) are selected by a Kernel density estimation strategy.

• Sub-pixel accuracy was maintained on real images even in presence of high noise levels.

• Isophotes analysis reduces the influence of the used edge map on the results.
