To　ensure　the　quality　of　watermarked　image　and　improve　the　embedding　capacity　of　watermarkings,　an　adaptive　image　reversible　watermarking　method　based　on　interger　transform　is　proposed　in　this　paper,　which　defines　a　new　generalized　integer　transform　algorithm.　Through　the　use　of　the　method　the　image　blocks　of　arbitrary　sized　are　transformed,　producing　certain　redundancy　data　that　can　be　used　for　watermarking　embedding.　In　addition,　the　parameter　m　used　for　integer　transform　is　adaptively　selected　according　to　the　variance　of　every　image　block,　hence　allowing　for　embedding　more　data　bits　into　the　smooth　blocks　while　avoiding　large　distortion　generated　by　complex　ones,　and　thus　the　algorithm　ensures　a　higher　embedding　capacity　and　better　quality　of　watermarked　image.　Compared　with　similar　algorithms,　the　experimental　results　show　that　the　proposed　method　has　larger　maximal　embedding　capacity　and　taking　Lena　as　a　host　image,　the　real　payload　can　reach　up　to　2.36　bpp.　The　proposed　integer　transform　algorithm　is　simple;　through　adaptively　interger　transforming　and　data　embedding,　the　quality　of　watermarked　image　can　be　assured　and　the　method　offers　a　large　real　payload.
