Abstract

We propose an automated morphology reconstruction method for curvilinear network analysis. The proposed approach first projects samples to the ridge of the intensity image of the curvilinear system. Then, a manifold deviation measure is utilized to approximate the ridge with piecewise linear segments between the projected samples. A nonparametric system workflow based on the kernel interpolation and density estimation is provided for the derivations without any user defined meta-parameter, i.e. hard threshold for segmentation. Lastly, a rigorous sampling strategy using the manifold deviation measure that can be used for robust sparse tree reconstruction is provided. The proposed approaches have been tested on a small set of representative retinal scans. Preliminary qualitative results indicate the effectiveness of the method.
