Hausdorff metrics are used in geometric settings for measuring the distance between sets of points. They have been used extensively in areas such as computer vision, pattern recognition and computational chemistry.While computing the distance between a single pair of sets under the Hausdorff metric has been well studied, no results were known for the Nearest Neighbor problem under Hausdorff metrics. Indeed, no results were known for the nearest neighbor problem for any metric without norm structure, of which the Hausdorff is one.We present the first nearest neighbor algorithm for the Hausdorff metric. We achieve our result by embedding Hausdorff metrics into l1 and using known nearest neighbor algorithms for this target metric. We give upper and lower bounds on the number of dimensions needed for such an l1 embedding. Our bounds require the introduction of new techniques based on superimposed codes and non-uniform sampling.
