The chord intersection technique does not require any gradient information which may be sensitive to noise meanwhile for the CHT technique, the gradient information has been used. In this research, the coconut was selected as the object of interest. 40 images have been experimented to evaluate the performance of the techniques and the detection rate for the CHT is 92.5% and 85% for the chord intersection technique. The average computational time for chord intersection technique is 0.1495s by CPU (AMD Athlon 64×2 Dual core 3800) 2GHz meanwhile CHT consumed more time, 2.3871s in detecting the circular pattern. 2009-08-13T03:13:30Z 2009-08-13T03:13:30Z 2007-07 Article p.115-120 0-7695-2901-1 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=4271730 http://hdl.handle.net/123456789/6871 en Proceedings of the Geometric Modelling and Imaging (GMAI 2007) Institute of Eelectrical and Electronics Engineering (IEEE)
