High‐payload block‐based data hiding scheme using hybrid edge detector with minimal distortion
Hsien‐Wen Tseng, Hui‐Shih Leng · IET Image Processing · 2014
Data hiding is a technique that is embedding the secret message into the media. In 2010, Chen et al.’ s proposed a scheme combined the ‘Canny’ edge detector and fuzzy edge detector to increase edge pixels, and embedded more secret data into the edge pixels than the non‐edge pixels based on the least‐significant‐bit (LSB) substitution scheme. In this study, the authors use Kaur et al.’ s fuzzy logic‐based algorithm and extend the original design to block‐based design. The experimental results show that the proposed method achieves higher payload with Kaur et al. 's fuzzy logic‐based algorithm, and achieve minimal distortion by selecting the number of edge pixel's embedding length of each block which has minimum mean‐squared error.
