A New Approach for Modelisation of Ellipsoidal-based Shape

In this paper, we propose a new method to detect ellipsoidal shapes. This method combine two well known approach : the Modified Hough Transform and the Elliptic Fourier Decomposition. The applications of this method are, for instance, medical imaging (ultrasound imaging, X-rayed, . . .), biological imaging (cell count) or intelligent vision in robotic. We have apply our method to the particular problem of cranial outline of fetus in ultrasound imaging.
