Abstract

We present a new scheme, which is based on the cost of interactively correcting detection errors, for performance evaluation of engineering drawings recognition algorithms. We correct an actual output graphic objects so that they to the expected output in a graphics editing tool using GUI, like Autocad. Through experiments, We define the time spent on the editing operations as the output element’s editcost, which we use as a performance evaluation index.
