Abstract
This project examines and enhances various forms of evaluation functions used in the comparison and optimization
of image segmentation algorithms. It defines quantitative criteria for definition of the evaluation functions and uses
them in the design and selection of these functions. It also investigates the relationship between errors in landscape
pattern metrics and segmentation and classification algorithms. Finally, it coordinates the creation of a repository of correct segmentations of aerial and remotely sensed ecological imagery to improve algorithm development by making rigorous comparison of algorithms possible.
