Some video processing and computer vision methods consist of several (weak) sub-algorithms whose individual decisions are integrated to reach a (strong) final decision. We present a framework for active fusion of sub-algorithm decisions based on the well-known least-mean-square (LMS) adaptive filtering algorithm. The weights corresponding to individual sub-algorithms are updated on-line using the proposed adaptive method in the training (learning) stage. The error function of the adaptive training process is defined as the difference between the weighted sum of decision values and the decision of an oracle (operator). Individual decision results are updated by making orthogonal projections onto hyperplanes defined according to the decision of the operator for the next stage. The proposed decision fusion method can be used in semi-automated video surveillance applications. A video based wildfire detection system will be presented as an example.

A. Enis Cetin got his Ph.D. degree from the University of Pennsylvania in 1987. Between 1987-1989, he was Assistant Professor of Electrical Engineering at the University of Toronto. He has been with Bilkent University, Ankara, Turkey, since 1989. He spent 1996-1997 academic year at the University of Minnesota, as a visiting professor. He is currently visiting Ryerson University.

He carried out contract research for both governmental agencies and industry including Bell Communications Research (Bellcore), European Community FP6 and FP7, Visioprime, UK, Honeywell Video Systems, Grandeye-UK, Creative Labs, National Science Foundation-USA, NSERC-Canada and ASELSAN, TUBITAK, Ankara, Turkey. He was a scientific committee member of the EC FP6 funded Network of Excellence (NoE): Multimedia Understanding through Semantics, Computation and Learning (MUSCLE) consisting of more than 40 institutions and labs.

Prof. Cetin was an Associate Editor of the IEEE Trans. on Image Processing between 1999-2003. Currently, he is on the editorial boards of journals Signal Processing and Journal of Advances in Signal Processing (EURASIP), and Journal of Machine Vision and Applications (IAPR), Springer. He is a member of the DSP technical committee of the IEEE Circuits and Systems Society and the SPTM committee of IEEE SP Society. He was Signal Processing and AES Chapter Coordinator in IEEE Region-8 in 2003. He was the co-chair of the IEEE-EURASIP Nonlinear Signal and Image Processing Workshop (NSIP'99). He was the technical co-chair of the European Signal Processing Conference-EUSIPCO-2005. He is on the organizing committee of International Conf. On Pattern Recognition (ICPR) to be held in Istanbul in Aug. 2010.
