Abstract: As the stroke constitutional complexity of shapes and texts is different, this paper proposed a shape and text separation method based on the calculation of the entropy of the strokes. Because the entropy of a document may vary with stroke size, adaptive resampling was introduced to handle different writing stroke sizes. In addition, the paper employed a symmetrical judgement mechanism to handle the separation of texts and shapes with equivalent stroke constitutions. The experimental results demonstrate the effectiveness of the proposed method.
