Combination of global and local contexts for text/non-text classification in heterogeneous online handwritten documents

作者:

Highlights:

• We present a method to combine global and local contexts for text/non-text classification in online handwritten documents.

• Global context refers to the feature vector sequence of an entire document and local context refers to the prediction of directly adjacent strokes.

• Global and local contexts are integrated by using a simple marginal distribution and basic combination rules.

• We propose multiple classifier combination strategies for combining global and local contexts to improve classification accuracy.
