摘要

Computer vision involves a lot of decision making under uncertain circumstances. In this dissertation, we propose a new information fusion method for decision making. The proposed method is capable of aggregating and propagating degrees of satisfaction of criteria in a hierarchical network, where the various nodes in the network represent sub-criteria at different levels of abstraction. The inputs to each node are the degrees of satisfaction of criteria, and the output is the overall degree of satisfaction. The proposed approach is very flexible since the type of connective at each node can be chosen by training algorithms. The training methods treat a set of the fuzzy-set-connective-based aggregation operators as activation functions, and determine the desirable aggregation connectives and the associated values of parameters as in a back-propagation neural network. In addition, the training algorithms can detect redundancy and reduce (or eliminate) the weights connected to the input which provides redundant information. At the end of training, the network can capture a knowledge base in a structure of connectives, and the structure can be used for fusion and propagation of uncertainties generated from various information sources. Through an extensive simulation study ranging from simple logic operations to object recognition, we show the effectiveness of the proposed method for decision making, especially for computer vision. Even though the scheme is based on the fuzzy set theory, we believe that any type of uncertainty including probability and Demster-Shafer belief measure as well as possibility can be adopted in the proposed framework in a practical sense.
