Abstract
An apparatus and method for detecting a circle are provided. The apparatus includes an edge detector configured to generate a foreground image from a background image generated from an input image and generate edge pixel information from the foreground image, and a voting processor configured to calculate a position of a central point and a radius of a circle by performing a circle Hough transform using the edge pixel information.
Claims18
An apparatus for detecting a circle, the apparatus comprising:
- an edge detector configured to generate a foreground image from a background image generated from an input image and generate edge pixel information from the foreground image;
