發(fā)布時間:2018-10-04 22:00
【摘要】:針對可用于圖像篡改的內(nèi)容感知縮放技術(shù),提出了一種基于概率Map圖統(tǒng)計特征的內(nèi)容感知縮放檢測算法.該算法利用概率Map圖以反映圖像是否經(jīng)過內(nèi)容感知縮放操作,并利用新提出的積分投影與局部統(tǒng)計特征來檢測篡改圖像.而后利用分類器進行分類訓(xùn)練,從而有效識別基于內(nèi)容感知縮放操作的圖像篡改.實驗結(jié)果顯示,所提算法能夠區(qū)分出原始圖像與篡改圖像,并具有較高的正確檢測率.
[Abstract]:A content-aware scaling detection algorithm based on the statistical features of probabilistic Map diagrams is proposed for content-aware scaling techniques which can be used for image tampering. The algorithm uses probabilistic Map diagrams to reflect whether the image has undergone content-sensing scaling operations, and uses the newly proposed integral projection and local statistical features to detect tampered images. Then classifier is used for classification training to effectively identify image tampering based on content-aware scaling operation. The experimental results show that the proposed algorithm can distinguish the original image from the tampered image and has a high detection rate.
