A　new　invariant-generation　scheme　is　presented　for　overcoming　high　order　moments　instability　and　noise　sensitivity.　By　selecting　orthogonal　basis　function,　phase　function　is　constructed.　Regarding　the　phase　function　as　model　function,　new　moment　invariants　were　generated.　This　method　combines　the　global　invariants　with　local　features.　Analysis　and　experiments　indicate　that　this　method　can　find　the　new　invariants　effectively　and　leads　to　a　better　retrieval　results.
