Detection of Zero Baseline Sinusoidal Curve Based on Randomized Hough Transform

Three basic problems: the minimum points set,converging mapping,dynamic link table of Randomized Hough Transform(RHT) of zero baseline sinusoidal curve are studied.The improved method for the fitting of a sine curve with three sample points is proposed.A detection algorithm of a sort of zero baseline sinusoidal curve based on RHT is given.The performance of computation and the storage is analyzed.Simulation experiment shows that the method proposed is effective.
