成果介绍

本发明公开了一种图像判别方法、存储设备及移动终端，方法包括：选取图像进行JPEG压缩时产生的DCT系数，并从DCT系数中按zigzag顺序选取前20个AC系数子带，组成对应的输入张量，按照一定的组织方式输入至对应的分支网络结构中；分支网络结构中的卷积模块对输入张量进行卷积操作、批量归一化处理、非线性化操作以及数据降维处理，将处理后的张量数据合并后输入至分类模块；分类模块将分支网络结构输出的张量数据进行分类，使用交叉熵损失函数对分类结果进行计算，根据计算结果判断图像是否经过双重JPEG压缩。本发明提高了图像是否经过双重JPEG压缩的检测准确性，有效判别图像是否别篡改，且无需对图像进行预处理，避免人为因素对判别结果的影响。
