英文例句/中文翻译:
This paper presents a digital image hiding technology based on chaos systems, it permutes images by chaotic system, then hides the multiple images into one image by using iterative blending based on chaotic system.
给出了一种基于混沌系统的图像隐藏技术,利用混沌系统对图像进行置乱加密,再利用混沌序列通过迭代混合将多幅图像隐藏于一幅图像之中。
The key of detecting and seperating permuting images is to find characteristic difference, which can be shown when permuted alias image is projected on a characteristic domain.
检测和分离出置换图像的关键是找到置换图像和被置换图像之间特征差异,即找到显现特征差异的特征域。
Then, the masked watermark is used to modify the 4th, 5th, or 6th bit of the corresponding pixels in the permuted image.
其次,将加密水印嵌入到变换图像位平面的第4、5、6位;
