Fast implementation of circular Hough-transform

A circular Hough-transform without loops.

Description

A fast implementation of the Hough-transform for detecting circles within an image. No loops are used! Cautions have to be taken that the input edge image has not too many edge pixels as out of memory errors may then occur.

• Acknowledgements: This submission has inspired the following:; Hough Transform for Circle Detection (GUI)
• MATLAB release: MATLAB 6.1 (R12.1)
• Other requirements: rather high memory usage to build the accumulator

It's for fixed radius.

Do you have FHT in MatLab for linear line detection?

Thanks.

Hi memory requirements but it's quite a smart solution to avoid loops; pretty accurate, expecially when target circle radius is big wrt image size.

Gran trabajo por esa transformada de Hought circular he quedado impresionada, seguid asi chicos.

Clever but slow
