AI Technical Summary

Technical Problem

Existing digital image splicing tampering detection methods suffer from problems such as insufficient continuity in identification, a large number of discrete points, and low robustness when recognizing the outline of spliced ​​regions, making it difficult to provide clear spliced ​​region localization.

Method used

By combining superpixel segmentation and color filter array interpolation, binarization is performed by establishing the squared difference matrix of pixel values ​​before and after re-interpolation. Laplacian edge detection is used to eliminate discrete points and fit a clear stitched contour.

Benefits of technology

It improves the accuracy of locating the spliced ​​and tampered areas, provides a clearer outline of the spliced ​​areas, and enhances the reliability of image forensics.

Abstract

本发明公开了一种图像拼接篡改检测方法、电子设备及存储介质。方法包括:读取待检测图像;采用超像素分割方法对待检测图像进行分块处理;模拟颜色滤波阵列的插值过程,对完成分块处理的待检测图像进行重插值操作,估计待检测图像的原始图像模式;建立重插值前后像素值的平方差矩阵,对平方差矩阵进行二值化处理,获得初步定位结果图;对初步定位结果图中的特定图像块进行边缘检测,得到边缘检测结果图;利用边缘检测结果图消除初步定位结果图中的离散点,将新的初步定位结果图中不连续的拼接区域轮廓补全为清晰连续的轮廓,完成拼接篡改区域的具体定位。实现提高拼接篡改定位的准确性,更好地为图像取证提供依据。
