Abstract: A method for binary distance transform includes identifying a first binary vector and a second binary vector, the first binary vector and the second binary vector both having a binary dimension m, the binary dimension m indicating a number of bits. The method also includes determining a first distance between the first binary vector and the second binary vector, the first distance including a count of differing bits between the first binary vector and the second binary vector. The method also includes transforming the first distance to a second distance. The method also includes executing, by one or more processors, a machine-readable instruction in view of the second distance.

Abstract: A method includes identifying a feature vector with N features to transform into M bits. The feature vector including one or more values, where each value corresponds to a characteristic of an object. The method includes applying a transform to the feature vector to create a transformed feature vector. The method further includes quantizing the transformed feature vector to generate a binarized feature vector of M bits.
