In this paper we introduce a new 3D object retrieval model inspired by some well-known mechanisms of the human brain: viewer- centric recognition, Markovian estimations, and fusion of information originating from the visual and vestibular subsystems. We have built a Hidden Markov Model (HMM) framework where 2D object views correspond to states, observations are coded by compact edge and color sensitive descriptors, and orientation sensors are used to secure temporal inference by estimating transition probabilities between states. Our first evaluation results, over a database of 100 3D objects, are very encouraging: the fast and memory efficient new method outperformed previous models. |
