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 graphic objects so that they match the expected output in a graphics-editing tool using GUI, similar to that of AutoCad™. Through experiments, we define the time spent on the editing operations as the of the output element, and use it as an index for evaluating the performance of graphics recognition.

Introduction
Performance evaluation of automatic engineering drawings vectorization has been proposed in several ways, including the number of matches (Kong et al. 1996, Hori and Doermann 1996, and Phillips et al. 1998), detection accuracy (Liu and Dori 1997, 1998), and (Phillips and Chhabra 1999). These proposed protocols provide indices for parison among vectorization systems. However, for practical
