摘要：

According　to　the　Matched　Filtering　Principle,　propose　a　new　method　of　convolution　power　spectrum　(CPS)　to　detect　the　activity　of　brain　function.　Firstly,　calculate　the　fMRI　time　series　and　the　convolution　of　fMRI　image　signal　of　experimental　model.　Then　PSD　of　convolution　signal　is　used　to　quantitative　analysis　the　energy　changes　of　blood-oxygen-level　dependent　(BOLD)　signal.　To　compare　the　SPM　PS　SVM,　experimental　results　show　that　CPS　algorithm　is　effective　to　analysis　the　brain　active　information　about　fMRI　time　series.　©　Copyright　2016　American　Scientific　Publishers　All　rights　reserved.
