In　order　to　achieve　smooth　and　continuous　panorama　stitching　effect,　an　image　fusion　algorithm　which　based　on　contrast　pyramid　and　combines　color　space　conversion　and　Contourlet　transform　is　proposed　by　considering　the　characteristics　of　panorama　stitching.　Firstly,　luminance　information　of　images　is　calculated　using　HSI　transform.　Then　contrasting　pyramid　based　Contourlet　transform　is　used　to　decompose　luminance　information　to　get　sub-band　information　of　images.　Finally,　images　are　reconstructed　by　fusing　different　sub-band＇s　information.　Experimental　results　show　that　the　proposed　algorithm　which　leverages　the　contour　features　of　Contourlet　transform　and　the　detail　information　of　images　could　achieve　good　effects　on　panorama　stitching　fusion.
