From: Jason Hu on 22 Mar 2010 22:37 Hi, I am working on quantification of fiber orientation via image analysis. I found a paper http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2690830/ where they used Hessian matrix to find the principal curvature of the fiber in image. I could reproduce the process up to the point where it requires Hessian matrix. Could someone point me to the right direction on how to apply Hessian matrix to the image to find principal curvature? Thanks! Jason
