Flexible Sequence Matching technique: An effective learning-free approach for word spotting

作者:

Highlights:

• Flexible Sequence Matching (FSM) is introduced here and applied to word spotting.

• FSM can do partial matching, skip outliers, and one-to-one/many correspondances.

• FSM is able to spot words inside segmented lines or from improperly segmented words.

• FSM can handle word derivatives and spelling variations.

• FSM can behave as other sequence matching techniques (DTW, MVM, CDP).
