摘要：

The evaluation of image analysis algorithms for constructing discontinuity trace maps was is discussed. To maintain high recognition and low error rates, individual threshold values were adjusted for each operator and after fine tuning an optimal threshold value was obtained for each image. A comparative study of different edge and line detectors was also done.
