Multiresolution Stochastic Modeling

A fast multiresolution algorithm for automatic detection/recognition of traffic signs.

We have made several significant extensions to our methodology for constructing multiresolution models for random fields, resulting in models that yield both visually and quantifiably accurate models and reconstructions for a wide variety of phenomena. We have demonstrated the method constructing low-order multiresolution models from complex random fields. This modeling methodology has also been applied to multiresolution imagery. The models have been used as part of a discrimination test, with results that show considerable improvement over current baseline system. We seek a framework in which to answer efficiently two key questions: (1) When do current object recognition, estimation and tracking systems break? (2) Where are the key hard parts of the recognition, estimation and tracking problem? Fig. 3 shows an automatic recognition of traffic sign for real-time and autonomous navigation.
