Abstract：Atpresent，forpatientswithsevereretinitispigmentosaorage-related maculardegeneration，retinalprosthesisis stiltheironlyectivemeansofvisualrehabilitationInviewofthis，animageprocessngstrategyhichachievesiagestyle conversionbytheAdalNalgorithmisproposedinordertoachieveaccuraterecognitionof expressonsunderprostheticvision.In thisstrategy，theoriginalfaceimageisconvertedintoasketchyfaceimageandkeyfacialpointsaremarkedwiththeDlib library.Thefaceregionistheninterceptedbasedonthesekeypointcoordinates，followedbyapixelationprocessAcomparative studywas madeontheexpresionrecognitionefectsof theoriginalimageandthatof the proposed methodundernormal human vision.Additionallyheexpressionrecognitionefectsoftheproposedmthodatthrrsolutions（2424322and4848） werecomparedwith thoseoftheoriginalimagedirectlypixelatedundersimulatedprostheticvision.Theexperimentalresults showthatheaccuracyratesfortheexpressionrecognitionefectsoftheoriginalimageandtheproposedmethodundernormal human vision are 71.58% and 60.41% ，respectively. The proposed method is proved to be more beneficial for expression recognition at low resolutions of 24×24 and32×32 in comparison with the method of pixelating the original image directly.
