Abstract：Deep learning model basedonconvolutional neural network（CNN） haveachieved significantbreakthrough in biomedicalimagesegmentationandhavebeen widelyappliedinpracticalscenarios.Theaccuracyof nucleus imagesegmentation playsacrucialroleinpathologicaldiagnosis.However，theexistingnucleussegmentationalgorithsstillsuferfromisuessuch asfuzzyandadherentboundaries，soanimagesegmentationalgorihmbasedonimprovedU-Netisproposed.Inthemodel，a tripleattentionmoduleisutizedtoenhancefeature focus，andfeaturefusion module，AGgatemodule，andlightweightInception moduleareincorporatedtoimprovesegmentationaccuracy.Theproposedalgorithmwasvalidatedonthe2O18DataScienceBowl （DSB2018）dataset.The evaluationmetrics including IoU（intersectionover union）and DSC reach 81.85%and 90.00% respectively.Experimentalresultsdemonstratethatincomparisonwiththeothersegmentationmodels，theproposedalgorithm exhibitssignificantadvantagesintermsof theconformitybetweensegmentedresultsandgroundtruthlabels，achievingsuperior performance.
