摘要

复制-移动伪造检测已成为数字图像取证领域的一个重要研究热点。复制-移动伪造是指将图像中的某个区域复制并粘贴到同一图像中。除了检测的鲁棒性和准确性问题外，CMFD还面临着时间复杂度问题。解决这个问题的方法之一是在CMFD管道中加入预处理步骤。本文综述了预处理步骤的重要性，以及降低复制-移动伪造检测时间复杂度的现有技术。采用离散小波变换(DWT)作为预处理技术进行了实验，以评估采用预处理技术在CMFD管道中的性能。实验结果表明，处理时间显著减少，但检测精度有所降低。

Solving Time Complexity Issue in Copy-Move Forgery Detection Thru Pre-processing Techniques

Copy-move forgery detection (CMFD) has become a popular an important research focus in digital image forensic. Copy-move forgery happens when a region in an image is copied and paste into the same image. Apart from the main problem of detection robustness and accuracy, CMFD is struggle with time complexity issue. One of the options to resolve this problem was by including pre-processing step in CMFD pipeline. This paper reviews on the importance of pre-processing step, and available techniques in reducing time complexity of copy-move forgery detection. An experiment using discrete wavelet transform (DWT) as a pre-processing technique was carried out to evaluate the performance of adopting pre-processing technique in CMFD pipeline. The experimental result has shown a significant reduction in processing time with some trade off to detection accuracy.
