Contextual text/non-text stroke classification in online handwritten notes with conditional random fields

作者:

Highlights:

• We present a comprehensive study on the exploitation of context for text/non-text separation in free form online documents.

• The problem is formulated as a Conditional Random Field for labeling the document as a graph of strokes.

• Different sources of context (spatial, temporal…) are modeled as template cliques and combined in the CRF.

• Results on a public database determine new state-of-the-art performance.
