摘要

提出了一种基于整数离散哈特利变换(DHT)的简单方法，用于在数字图像中嵌入不同形式的数据。它不仅涉及的计算复杂性大大降低，而且还能容纳更多的有效载荷，并提供比现有方案更好的视觉质量。由于整数DHT的无损反转行为，所提出的技术也可用于从嵌入图像中无损检索嵌入数据以及主机图像

A Low Complexity Technique for Data Fusion in Digital Images and Lossless Retrieval

A simple technique based on integer discrete Hartley transform (DHT) is presented for embedding data of various different forms in digital images. Not only it involves significantly less computational complexity, but also accommodates considerably more payload and offers better visual quality over the existing schemes. Due to the lossless reversal behaviour of the integer DHT, the proposed technique can also be used for lossless retrieval of the embedded data as well as the host image from the embedded image
