A broad family of problems in computer vision and image analysis require edge and circle detection. This paper explores the properties of the Hough transform for such tasks, improving them under a novel implementation on commodity graphics hardware. We demonstrate both a faster execution and a more reliable detection under different scenarios and a range of parameters selection. Overall, a consistent 3-6 acceleration factor and beyond is achieved for a 500 MHz GeForce 7950 GX2 graphics card versus a typical 3 GHz Pentium 4 dual-core CPU.
