2D and 3D Shape Matching using Evolutionary Algorithms
Ahmad Faisal Mohamad Ayob
School of Ocean Engineering, Universiti Malaysia Terengganu, Malaysia
Organizers: K.Miura, K.Kanev
Biography:
Ahmad Faisal Mohamad Ayob is Senior Lecturer of School of Ocean Engineering at
the Universiti Malaysia Terengganu. He received a B. Eng. degree in Mechanical
Engineering from the Universiti Malaya and Ph.D. in Mechanical Engineering from
the University of New South Wales, Australia. He has been active in the area of
multidisciplinary design optimization since 2008 and has been a contributor to
several engineering-specific journals. His international experience includes
programs and consultancies in Australia, Malaysia and Indonesia. His current
research involves the study of the optimum design of marine vehicles that include
high speed craft, unmanned underwater vehicle and design robotics for ocean
application.
Abstract:
Shape representation plays a major role in any shape optimization exercise. The
ability to identify a shape with good performance is dependent on both the flexibility
of the shape representation scheme and the efficiency of the optimization algorithm.
In this article, the use of evolutionary algorithm is presented for 2D and 3D shape
matching problems. The shape is represented using B-splines, in which the control
points representing the shape are repaired and subsequently evolved within the
optimization framework. The efficiency of the proposed algorithm is illustrated
using three test problems, wherein the shapes were identified using a mere 5000
function evaluations. Extension of the approach to deal with problems of unknown
shape complexity is also presented.
