– H. Rabiei (INT-I2M) : The graph windowed Fourier transform : a tool to quantify the gyrification of the cerebral cortex 18 septembre 20153 septembre 2015 adminFrumam Carte non disponible Date/heure Date(s) - 18/09/201514 h 00 min - 15 h 00 min Catégories Pas de Catégories Abstract : The Gyrification Index (GI) quantifies the amount of folding\nof a cortical surface. In this talk, we show the efficiency of spectral\nanalysis to perform such a task, and in particular we explain how the\ngraph windowed Fourier transform can be used as a tool to define new\nGIs with multiscale properties. We propose two different GIs and study\ntheir effect on a set of subjects whose cortical surfaces are modeled with\ntriangular meshes.[
