In this paper, a new steganographic method is presented that provides minimum distortion in the stego image. The proposed encoding algorithm focuses on DCT rounding error and optimizes that in a way to reduce distortion in the stego image, and the proposed algorithm produces less distortion than existing methods (e.g., F5 algorithm). The proposed method is based on DCT rounding error which helps to lower distortion and higher embedding capacity.

在块中隐藏秘密信息：最小失真嵌入

在本文中，提出了一种新的隐写方法，该方法可在隐写图像中提供最小的失真。所提出的编码算法侧重于DCT舍入误差，并以减少隐写图像失真的方式对其进行优化，并且所提出的算法产生的失真比现有方法（例如F5算法）少。所提出的方法基于 DCT 舍入误差，有助于降低失真和提高嵌入容量。
