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.
