The document presents a novel steganography approach using reversible texture synthesis to embed secret messages by resampling a smaller texture image into a larger one. This method allows the extraction of both the hidden messages and the original texture, offering advantages such as embedding capacity proportional to the stego texture size, resilience against steganalysis, and the ability to recover the source texture. Experimental results demonstrate its effectiveness in creating visually plausible textures while enabling multiple embedding capacities.

1. STEGANOGRAPHY USING REVERSIBLE TEXTURE SYNTHESIS
ABSTRACT
We propose a novel approach for steganographyusing a reversible texture synthesis. A
texture synthesis processre-samples a smaller texture image, which synthesizes a newtexture
image with a similar local appearance and an arbitrarysize. We weave the texture synthesis
process into steganographyto conceal secret messages. In contrast to using an existing
coverimage to hide messages, our algorithm conceals the source textureimage and embeds secret
messages through the process of texturesynthesis. This allows us to extract the secret messages
andsource texture from a stego synthetic texture. Our approachoffers three distinct advantages.
First, our scheme offers theembedding capacity that is proportional to the size of the stegotexture
image. Second, a steganalytic algorithm is not likely to defeat our stegano graphic approach.
Third, the reversiblecapability inherited from our scheme provides functionality,which allows
recovery of the source texture. Experimental resultshave verified that our proposed algorithm can
provide variousnumbers of embedding capacities, produce a visually plausibletexture images,
and recover the source texture.
