成果介绍

本发明提出了一种显示器屏幕图像翻拍的鉴定方法、装置及存储介质，想将输入的JPG图像转化为灰度图像并对应获取第一图像特征，再将输入的JPG图像提取R通道分量、G通道分量、及B通道分量并对应获取第二图像特征，将第一图像特征与第二图像特征进行融合，得到JPG图像最终图像特征；将JPG图像最终图像特征传输至Ensemble分类器进行分类鉴定，得到输入的JPG图像是原始图像或是翻拍图像的鉴定结果。对于同一个数据内的分类准确率相比于已有的特征提取方法得到了提高。尤其对于跨库实验，本发明的准确率要高于已有的特征提取方法，适用性更广，并不局限于实验环境下使用，即使推广到实际应用也能确保极高准确率。
