A general method for generating a noise like key is proposed in this paper. Chaotic process of tent map function is used as a deterministic generator of noise like key and image storage and retrieval is completed in an algebraic form. 提出了类噪声索引(key)产生的一般方法,利用帐篷函数的混沌过程作为类噪声索引的确定性生成器,以代数的形式完成了图像信息的存储和恢复。
This thesis concentrate on the research of deterministic phase retrieval technology base on the intensity measurement. 因此,本文主要对在强度测量基础上的相位恢复进行研究。
