Abstract:	Identifying the anterior and posterior commissures as well as the mid sagittal plane in magnetic resonance brain images is a critical first step in the normalization process underlying group studies. We present a fully automatic algorithm that locates these structures with high accuracy. Estimates of all three landmarks are achieved first with a nonrigid registration algorithm and further optimization is used to refine these estimates. Extensive validation experiments involving both simulated and real data sets demonstrate the accuracy and robustness of the proposed method.
