    Abstract: The algorithm of effective geometric hashing of the facial feature hyperspace for the accelerated search of the most similar face descriptors by their cosine similarity is described in the present study. The algorithm includes 6 required stages of processing descriptors extracted by a neural network from face images. The first stage is filtration o... Show More
