传统上，拼接复原工作需由人工完成，准确率较高，但效率很低。特别是当碎片数量巨大，人工拼接很难在短时间内完成任务。随着计算机技术的发展，人们试图开发碎纸片的自动拼接技术，以提高拼接复原效率-Traditionally, mosaic restoration work to be done by hand, high accuracy, but the efficiency is very low. Especially when a huge amount of debris, artificial splicing is difficult in a short time to complete the task. With the development of computer technology, people are trying to develop shredding disc auto-splicing techniques to improve the recovery efficiency of splicing
