The technique is used to annotate a manipulation video sequence, which has an a priori known structure. The probabilistic aspect is introduced into syntactic recognition tasks via Stochastic Context Free Grammars. A step towards unification of syntactic and statistical pattern recognition . A more interesting question is whether it is possible to integrate these alternative solutions, in such a way that the integration excels the individuals in performance. These studies suggest the idea of a multiple classifier system.
Conflicts arise when two or more classifiers make different decisions.
The correct rate of decisions by each classifier, p, is assumed to be identical for all n classifiers. In his approach, a set of pattern primitives are first extracted from an image and represented by symbol strings. One approach has been to represent the images or objects in the form of graphs. Because of the representational power of graphs, much effort has gone into the development of efficient algorithms which can effectively match graphs. Two main approaches have been tried.
