In this paper, we propose some new degenerate tensor discriminants to determine the position of fiber crossing points in a given human brain white matter. This method utilizes the tensor elements obtained from DT-MRI acquisition for calculating these discriminants. We employed the relationship between the solutions and coefficients of the twice differentiated characteristic equation. We verified our proposal by using a synthetic tensor generated from DT-MRI data. Our proposal has shown effective on reducing the computation time for obtaining the degenerate points.
