A Hough transform-based method for fast detection of fixed period sinusoidal curves in images

The paper deals with research on detecting a kind of fixed period sinusoidal curve in images. A novel method based on the Hough transform is proposed for the purpose, which proceeds on two stages. The first stage locates the baselines of sinusoidal curves using a voting process. The second stage determines the amplitude and original phase of the curve corresponding to a baseline position using a 2D Hough transform. Experimental results are given for synthetic images with and without noise. Compared to the standard Hough transform, this method reduces computer storage and computation significantly, and saves much more time.
