Image　Style　transfer　techniques　can　be　applied　in　many　fields,　such　as　artistic　creation,　film,　and　television　special　effects,　etc.　It　is　a　hot　and　difficult　research　topic　in　image　processing.　With　the　rapid　development　of　the　mobile　Internet,　fantasy　pictures　created　through　style　transfer　and　shared　on　social　networking　sites　are　very　popular　and　hot.　The　style　transfer　algorithm　based　on　CNN　is　the　current　mainstream　method　because　of　its　speed　and　efficiency.　However,　the　current　style　transfer　methods　mainly　target　the　entire　image　and　lack　pertinence.　In　addition,　these　methods　always　over-transfer　style　features　and　lack　the　details　of　the　main　content　of　the　picture,　which　affects　the　aesthetics　of　the　resulting　picture.　In　this　paper,　we　mainly　studies　image　layered　style　transfer　technology　and　propose　a　new　style　transfer　algorithm　that　can　highlight　the　details　of　the　ROI　in　the　image　by　introducing　the　color　transfer　Reinhard　algorithm　which　can　enrich　the　diversity　of　style　transfer　methods　and　provide　people　with　new　creative　methods.
