Data Hiding in Images by Hybrid LSB Substitution
[[abstract]]In this paper, two hybrid LSB substitution image hiding methods are proposed. The first method couples two previous works, the optimal LSB substitution and the optimal pixel adjustment process (OPAP), to improve the quality of the stego-image.

A Lossy Compression Tolerant Data Hiding Method Based on JPEG and VQ
[[abstract]]A lossy compression tolerant data hiding method is proposed in this paper. The image which hides data is named a stego-image. Most of data hiding methods will lose some hidden data when the stego-image is compressed by iossy compression ...
