This ability is improved through learning from our everyday experience. Our research goal is to providing such significant ability of learning to recognize various kinds of information to computer.Weareinvestigatingmethodsforimageunderstandingsuchasimagemodelingbasedonprobabilistictopicmodels,imagesegmentationviaenergyminimization,recoveryof3Dstructurefromimagesequence,Ourresearchinterestalsoincludecomputergraphicssuchasphoto-realisticrenderingalgorithms.Thesetechniquescanbeusedforvariouskindsofapplicationsincludingcontentbasedimagequeryontheweb,human-computerinteraction,MinoruMaruyamaProfessorSince 1996, he is with ShinshuUniv.
