This　paper　concerns　the　problem　of　the　wide　filed-of-view　on　intelligent　video　surveillance　system　and　presents　an　image　mosaics　solution　based　on　scale　invariant　feature　transform　(SIFT)　algorithm　to　get　the　wider　view.　Image　mosaics　contain　mainly　two　parts:　image　registration　and　image　fusion.　The　SIFT　algorithm　is　improved　to　meet　the　requirements　of　the　intelligent　video　surveillance　system,　and　the　SIFT　feature　points　are　extracted　efficiently　for　image　registration　in　this　paper.　©　2010　IEEE.
