A　still　image　is　usually　insufficient　to　depict　a　high　contrast　scene.　Exposure　fusion　can　enhance　the　high　dynamic　range　details　of　an　image.　A　robust　algorithm　for　multi-exposure　images　fusion　is　proposed　in　this　paper.　In　our　algorithm,　an　overall　luminance　layer　and　local　details　are　combined　to　generate　an　image　that　can　describe　a　High　Dynamic　Range　scene　more　efficiently.　A　base　layer　is　introduced　to　solve　the　luminance　reversion　problem　in　the　output　image.　The　details　are　reproduced　according　to　an　exposure　selection　procedure.　Experimental　results　show　that　the　proposed　method　is　more　robust　than　compared　algorithms.
