Cortical thickness estimation performed in vivo via magnetic resonance imaging (MRI) is an important technique for the diagnosis and understanding of the progression of Alzheimer's disease (AD). Directly using raw cortical thickness measures as features with Support Vector Machine (SVM) for clinical group classification only yields modest results since brain areas are not equally atrophied during...
To overcome the weak correlation between space charge and conduction current caused by individual measurement, a specialized system based on pulsed electro-acoustic method (PEA) was designed to perform simultaneous measurement of space charge and conduction current for plate sample. Firstly, electric pulse response during space charge measurement was simulated to analyze the interference during conduction...
We present a method for shape matching that approximates group-wise shape registration by reducing the problem to a 1-D registration. First, a novel medial curve method is proposed for computing a 1-D description of the shape. Second, a group-wise registration of the geometric descriptor is performed by directly minimizing the group variance. The resulting registration is used to adjust a global shape...
