The proposed approaches in the literature are either HMMs with one-dimensional (1D-HMMs) or two-dimensional (2D-HMMs) topology. Both have shown some serious drawbacks. The 1D-HMM approaches typically use a whole row (or column) of an image as observation vector and by consequence do not allow horizontal (or vertical) alignment. 2D-HMM approaches present some implementation issues because of the computational cost. In this paper, we propose a 1D-HMM approach which allow the use of local features and we will demonstate the accuracy of this approach on the so-called BANCA database.}, pdf = {https://publications.idiap.ch/attachments/reports/2005/rr05-17.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2005/rr05-17.ps.gz}, ipdmembership={vision}, }
