Exploiting forced alignment of time-reversed data for improving HMM-based handwriting segmentation

作者:

Highlights:

• Analysis of online handwriting segmentation boundaries obtained from HMM.

• Identification of early boundary problem in the Viterbi forced alignment.

• Exploration of time-reversed data for improving the segmentation boundaries.

• Incorporation of forward-reverse alignment in HMM based handwriting segmentation.

• Proposal is evaluated by improve in word recognition performance.
