The goal of quick response (QR) codes aims at convenience-oriented applications for mobile phone users. People can use the mobile phone cameras to capture the code with random patterns, usually displayed at the corner of web page, and then the hyperlink corresponding to the QR code can be accessed. Since QR code looks like random noise, its existence can greatly reduce the value of the original image...
Reversible data hiding can be classified into two major research branches, one is by use of the histogram of original image, named the H scheme, and the other is by manipulating pixel relations between adjacent pixels, called the difference expansion (DE) scheme. Both schemes have their own advantages and drawbacks, but the inherent characteristics of original image are seldom considered in existing...
In this paper, we present the intelligent multimedia data hiding techniques and their possible applications. An introduction on intelligent multimedia data hiding is described which covers backgrounds, recent advances, methodologies, and implementations. The recently developed research branch called reversible data hiding is also depicted. Two major classes for the implementation of reversible data...
