视频监控系统DSP底层软件的开发方法
Title:DevelopmentApproachesforDSPSoftwareinVideoSurveillanceSystems
Abstract:
Inrecentyears,thedemandforvideosurveillancesystemshasbeenincreasingrapidlyduetothegrowingconcernsforsecurityandsafety.DigitalSignalProcessors(DSPs)playacrucialroleintheeffectivefunctioningofthesesystems,providingreal-timeimageandvideoprocessingcapabilities.ThispaperaimstoexplorevariousdevelopmentapproachesforDSPsoftwareinvideosurveillancesystems,emphasizingthesignificanceofefficientalgorithms,hardwareoptimization,andsoftwarearchitecture.Additionally,itpresentsacomprehensiveoverviewofthekeycomponentsinvolvedinthedevelopmentprocess.
