Figure 1

Basic process of examination paper autoscoring. (a) A sample examination paper which consists of both handwriting and printed text. (b) A subquestion with answers to be scored. (c) Handwriting touches or even overlaps with printed text. The red circle shows an example of overlapping characters. (d) The proposed method targets separation of overlapping Chinese characters into printed text (left rectangle) and handwriting (right rectangle). (e, f) After successful separation is made, postprocessing and autoscoring become feasible.
