    • The present invention provides an image processing system, which can reduce calculation time by alleviating a calculation load in assessing the occurrence of tampering of an image. For example, the image processing system of the present invention first identifies a type of a form of an image to be assessed in assessing the occurrence of tampering. Next, a characteristic amount of a certain region (flexible region) corresponding to the identified type of a form is extracted as a characteristic amount of the image to be assessed. Then, the extracted characteristic amount of image to be assessed and the characteristic amount extracted from a certain region in an original image are compared and the compared result is notified as the assessment result. A flexible region, to which a user writes, is preferably specified as said certain region.
    • 本发明提供一种图像处理系统,其可以通过减轻计算负荷来评估图像的篡改的发生而减少计算时间。 例如,本发明的图像处理系统首先在评估篡改的发生时识别要评估的图像的形式的类型。 接下来,提取与所识别的形式的类型相对应的特定区域(柔性区域)的特征量作为要评估的图像的特征量。 然后,比较提取的要评估的特征量的图像和从原始图像中的特定区域提取的特征量,并将比较结果作为评估结果通知。 用户写入的柔性区域优选地被指定为所述特定区域。
