Abstract: This paper investigates the cooperation of on-line and off-line handwriting word recognition systems. Our goal is to improve a mature on-line recognition system by exploiting the complementary information present in the off-line representation built from on-line signal. After describing the on-line and off-line HMM based handwriting recognition systems, we propose a formal framework, which allows describing different strategies for combining the two HMMs. These schemes are then evaluated on the UNIPEN database, both for isolated character and word recognition tasks.
