The research filed is multi-dimensional signal processing dealing with 2D image and 3D model.Denoisingby synthesizing textures of a flash image (left) and colors (also shadows) of a no-flash image (middle), and its output clear image (right).Image Processingfor More Clear Image CreationCreation of images based on human perceptual feeling. In an original image (left), the regions of photographic subjects (middle) are enhanced while other background regions are blurred.Mainlyimageprocessingisassociatedwithmakersproducingcameras,projectors,printers,andscanners.Thedemand,however,isspreadinginindustryalongwiththedemandsofimagerecognition.Ouralumniisnowactiveinelectronicsandcarmanufactures.After GraduationIn the FutureElectrical& Computer EngineeringStudentsdefinethespecificationanddesignacircuit.Tofabricateachip,acircuitdesignerdrawsalayoutwithnm-orderscalebyCADsoftware.VLSIchipandmeasurementboard.StudentsdesignandverifyaVLSIchiptoworkasrequired.KohJohguchiProgressesofelectronicsandinformationtechnologieshaveproducednewindustriesandservicesliketheInternet,amobilephone,etc.Espcially,thescalingtechnologyofVLSIrealizesawidevarietyoffunctionswithlowcost.Bythecommoditization,thematuredVLSItechnologyhasbeenusedinmanyareas.But,Japaneseelectronicsindustryisstrugglingwithcostcompetitiveness.Toovercomethis,wehavetodifferentiateproductsfromothersandcustomizeourVLSIchipwithacircuitdesigntechnology.Ourlaboratorywilldevelopanewcomputerarchitectureandsystemsbyco-designinghardware,softwareandapplication.“TrillionSensorsUniverse”iscomingupsoon.Trillionsensorscollectandcomputemanyinformationfromtherealworld.Then,VLSIcircuitdesignbecomesakeytechnologyformedicine,agriculture,husbandry,logistics,architectureandcivilengineering.Todistinguishproductsfromthecompetitorsandproduceuniqueproducts,VLSIinnovationisessential.Inourlaboratory,studentscanstudynotonlydigital/analogcircuitdesignbutessentialtechnologiesfromsensordevicestosoftware.Byresearchinginconsiderationoftheoutput,wewillplayavitalroleinthedevelopmentofInformationCommunicationTechnology(ICT).Asagraduationwork,studentsinJohguchiLab.proposeacircuitandarchitectureandusetheirinventivenesstotacklearesearchproject.Studentscanstudyawideareaincludingdevicephysics,measurementtechniqueandsoftwaredevelopment,etc.Also,successfulexperiencesofachievingsomethingbecomeusefulforthefuturejob.Associate ProfessorHe received the Ph.Ddegree from Hiroshima University in 2007.His research area is low power VLSI circuit design and computer architecture.
