This paper proposes a method of extending the optimal linear transformation (OLT), an image analysis technique of feature space, from magnetic resonance imaging (MRI) to functional magnetic resonance imaging (fMRI) so as to improve the activation detection performance over conventional approaches of fMRI analysis. The method was: (1) ideal hemodynamic(More)
The optimal linear transformation (OLT), an image analysis technique of feature space, was first presented in the field of MRI. This paper proposes a method of extending OLT from MRI to functional MRI (fMRI) to improve the activation-detection performance over conventional approaches of fMRI analysis. In this method, first, ideal hemodynamic response time(More)
Iris location is one of key steps in iris recognition system. Utilizing erosion operator, the inner-edge of iris was located. We reconstructed the 3D surface of eyeball by viscosity solution of Eikonal equation in shape from shading. According to the change rate between iris and sclera on the 3D surface, outer-edge of iris was picked up. For eyelids, a(More)
