| Research Abstract |
The objective of this research is to find general model structures which are robust to image variations for image recognition. Separable lattice HMMs (SL-HMM) have been proposed as statistical models which can deal with location and size variations. This research proposed a new model structure which integrates linear feature extraction based on probabilistic principal component analysis and factor analysis into SL-HMMs. Furthermore, SL-HMMs were extended to models which can represent rotation variations and which include explicit state duration models.
