Jeff Wigdahl – Progress Report 6

This reporting period my main contribution has been my work in optic disc detection and curvature enhancement. Both methods Progress Report 6proposed were able to outperform state of the art methods on publicly available datasets. Both methods are also very adaptable (this being the main feature of the tortuosity estimation). The curvature enhancement method has allowed for a new set of tortuosity metrics to be created. By changing the filter banks, these metrics can be adapted to better estimate the tortuosity evaluation of an individual grader.
